I wanted to make a little box that perfectly fit the extra nozzle included with my printer.

This version prints the sliding lid and base in one color on the same plate.

Tight tolerances! Tested with Bambu PLA Basic. The lids are perfect to me. I promise I did many tests - if the lid was 0.20mm smaller you wouldn't like how loose it was, and 0.20mm bigger would never open after you forced it shut. I tested these +/- 0.20 increments on the length, width, and height, before coming to this final fitment ratio. The current size was perfect on my printer after a slight break-in period using Bambu PLA Basic on X1C. PLA Matte was a little tighter but I still wouldn't change the geometry. The nozzle has ~1mm room around it.
