I recently bought the game GPS from Board Game Tables and couldn't fit everything back in the box. I found a few designs on thingiverse but the one I liked best had very thick walls and felt like a waste of filament. I used the dimensions and made my own design with 1.5mm walls and it worked great! Print 6 of the small box and one of the long box.
Idea by XopherNiven on thingiverse, created by me.
I have dozens of free designs here on printables, but if you are looking for more check out my Etsy shop Taylor Jane Design Co.
The author marked this model as their own original creation.
