Made to replace the terrible stock case on this style of super cheap 13 piece x-acto/hobby knifes that are easily found atleast in Finland and I suspect everywhere.

Print settings dont really matter, it'll be strong enough anyway so use what you like. I prefer voron print settings and with those the whole thing took 50g accent and 53g main color. https://docs.vorondesign.com/sourcing.html#print-settings
File name ending in [a] means you should consider printing it in accent color.
Print parts are not automatically oriented. Slicer auto-orientation should work, or print latches sideways and boxes flat on back.
Optional weather proofing seal that should be printed in TPU.
Uses 6x m3x20 SHCS screws that thread to plastic, installed from outside towards inside. Two for the hinges can be replaced with m3x16 SHCS.
Cut the stock magnetic strip a little shorter to fit.
The author remixed this model.
Changed to fit x-acto/hobby knives
