Additionally, assembling this puzzle requires 72 #4-40 x 3/8” screws, and super glue if you want to glue the caps in place. M3 screws of a similar length are likely to work as well. I can supply you with screws if you are unable to find ones that fit.
Contact me if you are interested in a fully assembled, stickered, and dyed version of this puzzle. I have a sticker template available if you’d like to cut stickers yourself, but I can also cut you stickers for a small fee.
