So, after having posted on social media about the boxes I built a finnish friend reached out to me asking for help in printing a box. He already had a design and proper 21700 batteries so I just threw something together in CAD and printed it out for him.
When I asked him for a logo to use he sent me a picture. I don’t know if he was serious or not but this is how it turned out:
He was happy with the result and the fit in the frame was more or less perfect.
Didn’t get many more pics of this project unfortunately, so this was just a quick update.. there’s still much more to come so stay tuned!
