I created these small interlocking bit holders to help organize the many bits for our Carvera desktop CNC machine. They angle the bits back a bit for easier viewing and snap together nicely with one another to allow for whichever configuration you like best.
I've included a version both with and without a hole for a 6x2mm magnet in case you'd like some additional support keeping them in place within a metal workbench drawer.
I've had success printing these on a Bambu Lab X1C with standard PLA settings other than swapping Inner/Outer to Outer/Inner.
No supports needed (the overhangs are a bit higher than the parts that fit into them to allow for a bit of sag from the bridging).
The author marked this model as their own original creation.
