I needed a box to store the 5 piece router bit set that I bought from Harbor Freight so I remixed a model and made this box. Should fit all the bits nicely, although I was a bit generous with the clearance for the shanks I think (8mm for a 6.4mm shank). I might add some foam to the lid to keep them from rattling around.
Added a new version where the top and bottom are the same height so it can be printed in place. It also moves the router bits up out of the bottom of the box so that you can grab them more easily.
The author remixed this model.
Remixed to fit a 5 piece router bit set and to actually be print in place. The original has different sized lid and bottom so it cannot be printed in place without a Ton of supports under the lid.
