Here’s the super quick version of our full walkthrough on how to assemble a Faux Neon Light using our file pack. The full, mostly slowed down, video is up on our YT : https://youtu.be/MiXrXgwzv40

We also released an updated version of the file pack that now includes all letters and numbers in horizontal format AND the medic symbol!

All of them can be made using an LED rope light and ZERO soldering!

Rose City Comic Con is in two weeks! Are you ready?!

We will be there with our booth again this year - trying a brand new layout and debuting a whole lot of new merch and goodies we haven’t shared anywhere else before (but will be available online after Rose City).

Come by booth 1019 and say hello and check out our new stuff! We’ll also have FREE badge ribbons - get yours before even more cons stop having physical badges :(

How amazing do RuthlessNightsister and AdoboVision look?! RuthlessNightsister used our Cly chest armor files in their build and made them look fantastic! We always love to see our stuff used out in the wild but seeing something we modeled actually be part of a release event for a Star Wars game?! 😱 we are absolutely floored and honored!

So far I’ve only played the first 2 sections of the tutorial but this game is already EXACTLY what I was hoping it would be! 😍

Did you know we take commission for paint/finishing work even on prints that aren’t ours? A customer printed their Titanfall helmet and armor but then didn’t want to do the finish work so hired us!

(They still wanted to do electronics, strapping, and the visor hence why they are missing)

Our custom designed version of Joyeuse from Halo: Infinite! Our client wanted something that read as Joy but was a more military styled pant and jacket versus a spandex suit. We used a combination of Lurex Chiffon and metallic embroidery thread to give it a digital look. We opted to 3d print the UNSC logo and lettering onto mesh to sew on as we couldn’t use HTV without ruining the delicate fabric but wanted to keep those details sharp and crisp.

We’ll be vending this weekend at and couldn’t show up with nothing Dungeon Crawler Carl related! This is the first of several designs we have in the works, but this will be available this weekend with a handful more keychains and stickers at RCCC in September.
