Perfect cubes with sliding lids!
Interior Dimensions with the lid closed are exactly:
Update: I suggest adding a brim on the boxes (not the lids). I will update the files to use a brim eventually.
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 that I will use going forward. 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. 50% Support Cubic Infill and no iron so I think it's about as fast as it can be.
