Labyrinth Box

Created as an exercise to help learn CAD in fusion 360. I used an online labyrinth creator to make the maze. My box features an easy close - there's a channel that runs the full depth of the box to the start position, with a barb to prevent the box being opened this way.

This is a work in progress - the barb is a small piece and the exact size required massively depends on your printer's tolerances, and probably a little bit of 'making' to make it work for you! The barb inserts into a small slot on the main base piece. Currently I need to place a small bit of plastic underneath the barb in order to tighten its fit. I would suggest experimenting by adjusting a single axis scale in your slicer - it's only a 3 minute print anyway so easy enough to iterate the exact scaling you need.

Regarding tolerances, I found that 0.25mm tolerance was too tight and 0.5mm too loose. The upload has a tolerance of 0.4mm, as yet untested. The fit tends to ease with use.
