3D Meetup 2019 - Recap

All Blogs, News & EventsKarl BadkinComment

What was it?
For those who haven’t already seen my previous blog about what 3D Meetup is and what I was up there, you can find my previous post by clicking here.

Today’s blog is going to be about what I witnessed with my own eyes as soon as I entered the doors during my first ever 3D Meetup visit.


To quickly summarise, 3D Meetup was an event held in April 2019 where people from around the world (but mostly Scandinavia) meet up to show off their projects, see the latest developments from big names including E3D, Dremel, FLUX, BONDTECH and other guests.

A big part of the event was partaking within the community project which I have discussed briefly here. Today’s blog will cover this is a little more detail though.

As soon as you enter:
Situated in Sweden and about 30 minutes away from Helnsingborg central you enter straight into a big lobby to see 3D printed RC F1 car projects and other builds zipping around a laid out track.


In-front of that was the drop off and build location for the community project being directed by Dinea Design.

The community project:
After dropping off my submitted pieces I finally noticed a welcome board of those who had participated. This took me by surprised and was great to see my name in writing alongside other contributors.


There was a total of 216 individual pieces to be gathered together from visitors who attended in person and people who posted in their 3D prints. I kept checking back throughout the day to see the progress of the build by Dinea and colleagues.


Unfortunately I wasn’t able to stay right up to the last 2hrs of the event due to travelling from the UK and having other plans too. However Dinea had since posted updates on her own blog that can be found here.

Guests and other businesses:
Once you walk through into the main hall the room has been split into 3 areas. The left side was full of exhibitors and vendors advertising products and services related to 3D printing. These vendors were aimed at both hobbyists but also providing problem solving solutions, software and machining to businesses on a much larger industrial scale too.

It was also great to come across two British organisations, these included 3D model hosting services My Mini Factory and E3D (someone I think I will be spending allot of money with soon…). Leading around that one side of the room we also had FUSION showing off their all in one machines for 3D printing, laser cutting and engraving, BONDTECH and more.


Big names also spread out into the central hall including Dremel DIGILAB. A brand that I will have a full blog dedicated to what I discovered on the day from their three machines to the filament range and what they bring to the education systems around the world and mad scientists at home in their man caves.

The hobbyists and mad scientists:
After all of the high end names, service providers and material shops you finally came across the many tables of hobbyists and mad scientists who had brought their printers and custom builds to the show to socialise and tinker away from home.


It was amazing how many people had brought over custom build machines from scratch. Here is a small collectionbelow to continue doing the rest of the talking.

It was great to also see certain people there showing off skills and developments to aid people in more ways than decorative home objects. PETRA DESIGN is a hobbyist looking to build a profile for lighting but also dabbling with prosthetic designs influenced by other creators found online, something I soon hope to expand into too on this website.

3D Meetup Recap Part 2:
To keep this blog short and sweet and not too much of a wall of text, I’ll be continuing my re-cap in the next week whilst working on other 3D printed projects. So stay tuned, and check back next week to see part two of 3D Meetup 2019.

3D Meetup 2019 Community Project Submission

All Blogs, News & EventsKarl BadkinComment

What is it?

A big part of the event that I’m most excited to see is my entry built within the 3D Meetup 2019’s community project. Hundreds of prints will be made from people all over the world of models pre-designed. Everyone can either get together or ship their part over to Sweden to have the following masterpiece constructed.


I don’t know if the art piece is going to be constructed on the first day, or over both days the event is being held. But once it is fully up, it’s going to be that tall you can walk through it! My chosen part is A-35.


The shape of it is slightly confusing and hard to figure out exactly where it is going to appear within the model, but it should be around head height when walking through. Below is a quick screen-grab of the model quickly loaded up in CURA for a visual.


Here is my piece:

The guys at 3D Meetup kindly included a recommended CURA profile to print the piece in.

Example Cura settings.JPG

Unfortunately all I had laying around in a big enough supply for a last minute entry was some eBay special yellow PLA filament. This was supposed to be neon yellow, I learnt the hard way after this old purchase and have only stuck to reputable suppliers since. But when in a pinch for something different, it’s all I had.

The results however are visually acceptable and the whole print is very robust! Considering there is only 20% infill the whole piece is holding up very nicely. The print was relatively fast at just under 3hrs too and was before my latest bolt on part cooler (more on this in a future blog).



After following the profile provided by Cura, I am a little concerned as to why the pegs are so loose fitting… hopefully everything will just hold together nicely with it’s own weight or a bit of glue will be used on the contacting edges.

The top surface that was printed last is also not sloped very smoothly, I doubt this is something to do with the settings, but the model is already prepared as an .STL to drop straight into any slicing software to then export to your printer.

The top face is also slightly stepped, again I don’t think this is a settings issue, and it definitely isn’t printer related. Hopefully the weekend will reveal all and everything will just slot together perfectly.

The big day:

So, with the piece printed and ready to go, this Saturday the 27th of April I’ll be handing the part over at roughly 10am. Fingers crossed I’ll get to see the whole construction completed, or at least my part added to the masterpiece by the end of the day. I’ll be sure to blog about the whole day upon my return the first week of May.

Below is a video highlighting what happened last year, here is hoping this weekend is even bigger.

Jack/F1/F2 3D Printed Trigger Installation Guide

All Blogs, How To GuidesKarl BadkinComment

So you’re ready to try something new?

The purpose of the 3D printed Jack/F1/F2 compatible triggers are to add a bit of perosnality/customisation to your HPA powered Airsoft rifle, as well as taking up most of the trigger slack without the use of grub screws.

The trigger does not need any spring and are sold in sets if 3, 2 different sizes and one without a pull limit bar (use with caution). This guide is a very simple “how to install” and modify if your gun has become too sensitive.

Out with the old, in with the new:

With your Jack/F1/F2 engine pre-installed (there are plenty of YouTube videos on how to fit one), take out your old trigger and throw your trigger return spring in your parts box/bin.

Now push the included steel pin into your hole of the 3D printed trigger and have your trigger exactly half way down the pin. This is a friction fit, there may be some play and for piece of mind you can use a bit of blue-tac, putty or a very light amount of glue to retain it, once you know what trigger you’l like to run the most.

Start by placing the trigger head in first, in-front of your Polarstar ECU micro-trigger.


You can only insert this trigger one way, with the dimple in first. You will have to half engage the trigger before then dropping the trigger into your gearbox casing with the steel pin.


Your trigger will stand by itself as pictured above, no need for special tools or three hands to then seal your gearbox casing together as normal.

Testing and tuning:

With your gearbox casings together, add a couple of screws in place and test your trigger lightly in all firing modes by moving your firing selector by sliding it with your fingers.


Ensure full auto stops firing as soon as your let go of your trigger! If your gun continues to fire or does not stop firing instantly, your trigger is pressing against your electronic trigger too much!

To fix this, check your ECU board is mounted square in your gearbox casing. If your ECU board is fine, then you need to lightly sand your trigger back a little to pre-engage your electronics lesser.


Now you need to check your trigger does not move side to side when your gearbox casing is all closed up. Simply grab the trigger lights and make sure there is no serious side movement, you need a little to allow the trigger to freely rotate and bounce on the steel pin.


If there is too much slack, you can simply add a normal gear shim to take up some free space, but try and keep your trigger as close to the trigger board as possible to prevent the 3D printer trigger over riding and then sitting on top of the Polar Star electronic switch.


Further tuning:

To make the trigger action even more sensitive, you could glue some tin foil or metal tape to the back side of the trigger or inside your gearbox casing. This pouch position your trigger contact face closer to your ECU board switch, but then you risk accidental firing too easily or constant firing. Be careful how extreme your go as it could also damage other components.

Trouble shooting:

If you have any further technical queries or need assistance with your build, feel free to send us a message through Instagram or Facebook messenger.

3D Meetup 2019

News & Events, All BlogsKarl BadkinComment

What is it?

3D Meetup has been around a few years and seems to be most popular in Sweden (from my current knowledge), and this year i’ll be there capturing highlights from the Saturday and submitting my own print, more on this later…

3D Meetup host large events for everyone who has a passion for the hobby, and also work within the industry to meet and show off new and exciting creations and socialise.


What’s going on there?

As well as stalls for hobbyists to show off their printed creations, custom built 3D printers and other inventions, there are also talks and presentations of new equipment from leading industry professionals. Organisations and exhibitors include:

  • E3D-Online

  • Micro Swiss


  • BuildTak

  • Fusion360

Plus many more, one of the most exciting parts i’m looking forward to are the talks too being held by the faces behind the names above and more, plus a hopeful chance of meeting faces such as RCLifeOn, Scott Lahteine, Daniel Noree and more.

To see a little more about the event from last year in more than words and pictures, check out their official YouTube video below.

The community project:

An event that I have entered! Hundreds of 3D printing enthusiasts have signed up to produce individual parts to come together or ship their creations in to build “Equilibrium”, a three legged pavilion aimed at being a community print.

A Voronoi pattern which is tall enough for people to actually walk though and is all push fit together. There are over 300 components to this masterpiece, and I cannot wait to see my own component in there. More on this will come in a later blog.

I cannot wait:

Unfortunately with this website going live to close to the event, I cannot say “say hello if you see me there” but I am very excited to be there, expand my knowledge in the 3D printing world and visit Sweden again. Bring on 3D Meetup 2019! (please don’t make me spend too much money on further upgrades whilst i’m there…)

General, All BlogsKarl BadkinComment


For those who have randomly come across this site, or found it from my social accounts, then welcome! This is just a brief introductory to what the site is all about and a little background history into myself, Karl Badkin, a guy who started off with a simple hobby then became addicted very fast (inserts best photo he has of himself below).

An exploration of Scotland when I was more addicted to photography in general.

An exploration of Scotland when I was more addicted to photography in general.

Why do, what I do?

Addiction. No matter the hobby, I very quickly explode and want to do everything possible in a very short amount of time. Whether it is Airsoft, cars, fishing or 3D printing, I have to learn as much about it as fast as I can, spend too much money in a short period of time… and take over the entire home with upgrades, parts and customised components.

My previous university studies include Complete Games Design at Huddersfield University, where I went to specialise in 3D modelling. I’ve modified games before attending University for titles including CRYSIS, Call of Duty and more. Before this I had previous CAD experience with Bennetts at the age of 16.

The purpose of this website is simply to host a sales page for the Airsoft related items and blog on my progress, learning and discoveries made throughout 3D printing. After being within the Airsoft industry for the last 9 years, most of my initial design and print work is aimed around that field of interest.

From my Airsoft background, I have also gained experience in product photography, online advertising and more, that is why currently, a lot of content on here is “Airsoft Toy Gun” focused.

Where am I going with this?

The plan, to obviously upgrade my printers and become even more addicted, whilst also sharing what I learn along the way. Reviews of what I use, what goes wrong, what I did to fix the problems and to also meet other people within 3D design, print and material production to eventually share what is going on in the world for this “hobby” of mine in which I am quickly expanding within.
