For the sake of a contest you can download missing files if you mosey on over to my makerworld page, all STL & .3MF files are there for an easy print, thanks in advance: https://makerworld.com/en/models/582129#profileId-503251
Sorry teacher, I shredded up my homework. The desk is your oyster, shred your pencil case, your textbook, your pencil, anything and everything with this simple fingerboard. Functional pencil case with a phone stand and a fun little toy for your kids to mess around with during recess or something you can mess around with between classes.
It's tricky but fun! Pun intended For the hinges; cut a couple pieces of filament, push them in and melt the ends.
I've included 3MF files for the smooth top or fuzzy skin top for some grip if you just want the fingerboard, as well as another file for the pencil case without the phone stand.
Enjoy!
