23-Slot Portable Rotary Burr Case
Hello. So I designed this compact case to keep my rotary burrs and engraving bits organized and easy to grab.
It holds 23 bits with roughly 2.5–3 mm shanks, with slightly deeper slots around the outside for easier access. The threaded lid keeps everything together, and the whole case stays pretty compact at around 66 × 66 mm.
I’ve also made a few other storage cases in a similar style for different tools, so feel free to check those out as well if you like the design. https://makerworld.com/en/models/3121988-23-slot-portable-rotary-burr-case
