I wanted a compact holder that could hold a bunch of dremel bits (mainly thin burrs etc.). I modeled this to hold 90 bits, but it will hold less if you're using polishing wheels, cut off discs, and other large diameter bits. I designed this in inches, so if if shows up tiny in your slicing software, change the scale to 2540 to convert mm back to inches. Most slicing software assumes the part is in mms so this is something I deal with all of the time. I printed this with no support, at 30% infill, and with 4 layers all the way around. The print turned out great, but you need to drill the holes if you have any stringing inside them. Let me know what you think and post those makes!
