Rainbow Box

thingiverse

This is an 85 step sequential discovery puzzle box with two internal compartments. I plan to put together assembly instructions in the near future, but in the meantime I posted a disassembly video on reddit (username: mowens995) that can be used for tips. All pieces are designed to be printable without supports, but depending on the calibration of your printer I would recommend using supports with the floor, subfloor and red .stl files. As for layer height - standard 0.3mm should be sufficient for most pieces, but I would recommend using a lower height (0.2mm works for me) on the Tools file. Tolerances and clearances are very tight on this design to allow it to function correctly. If your printer is decently calibrated, and don't use any specialty filaments (wood PLA specifically gave me a lot of trouble) a few passes along each piece's full range of motion should scrape off any rough edges and allow them to move smoothly. However, if you still have troubles, I've found that metal files or sandpaper help dramatically. This is also printable at 80% scale - which is my personal favorite size, however due to the scaled down clearances between pieces this version requires a decent amount of post processing to become completely functional.
