Incredible! I found this video by chance and I must say, you are easily my favourite tech-channel on the site! Subscribed! P.S.: I wondered if you could build a flamethrower like the one from Elon Musk, that would be really cool! :)
Yes, this is definitely my least favorite part about this project. The main problem I encountered when designing the box is the fact that the wooden boxes are apparently not normed and it is very hard to find the same size box in the eu and the us for example. Therefore the plastic parts have to be glued in place which is messy and hard to align properly. If you do want to try to build your own useless-box however, I have linked all the necessary files together with some more information on my blog: blog.hirnschall.net/diy-useless-box/
Hi, I am afraid ordering 3d printed parts will be very expensive. The best way I know of is probably jlcpcb or pcbway, although I have not used either personally. You are supposed to 3d print the parts yourself using the provided stl files. I hope this helps! A complete parts list is available at blog.hirnschall.net/diy-useless-box/ . It includes Amazon.de and Amazon.com links for all parts.
