Dremel - Milwaukee hand protector replacement nut – with COLLET WRENCH built in Credit to https://www.thingiverse.com/thing:2058773 this is a replacement Hand Protector Nut, for Dremel, and other rotary tools. IT IS A WORK IN PROGRESS, but my final print did work. Its MODIFICATION is that it has , at least for DREMEL, a COLLET WRENCH built in. Dremel, when they came out with the cordless drill, ADDED a square metal piece into the nose nut, and this acted as the WRENCH for the COLLET, which they made as square, so the NUT could be rotated any 90 degrees to contact the collet. Well, the OLDER collet just has two flat sides. But I always thought that a wrench-style could be incorporated there. SO, when I saw this current design above, I imported it to Sketchup, added a circle on top with a rectangle, in which one set of sides is 10.1 mm, which is the approx.. width of the collet flat sides. And it WORKS! – I can now ditch (95% of time) my wrench. To use it, you loosen the nut, and it comes free of the threads while still freely rotating beneath the collet. You then line up the narrower flat sides (mark them with magic marker), onto the collet, and you can loosen/tighten the collet with it. And, as original design, it slips fully over collet for removal if desired. AGAIN, this is a work in progress, more so to get it to show up correctly in CURA. CURA added one layer of print, ACROSS the rectangle, in one printing, and NOT in another, but SKETCHUP shows the rectangle as being open. So, if it DOES print with one layer in that rectangle, it was easy to slice out with utility knife. Anyway, hope this work in progress can help others with this wrench use.
