Dremel 3000 thread on holder.

thingiverse

Tried a couple on here and they didn't quite hit the mark, but after fine-tuning the threads, rotating them to perfection, scaling to size, adjusting the pitch slightly and adding a custom recess for the nose of the Dremel, erasing everything else - voilà! MSKA's Dremel protector was good to go. When tightened, the buttons on your trusty Dremel also serve as an important visual indicator, pointing out which is pretty crucial. I've even included the SketchUp file so you can modify it to suit your needs - it's manifold and prints flat with ease. Just a heads up: the recessed ring at one end of the threads points directly towards the Dremel for added convenience.
