This is an attachement for a dremel to replace the holder provided with the little bolt hobbit.
Its based on Router attachment for rotary tool by Lenbok (well the top part of it anyway).
Almost everything is panametric so the offset can be adjusted to get the hob in the perfect spot and to also get the perfect fit onto the dremel.
Like the router attachemnt is uses sylwch's thread library thingiverse.com/thing:8793.
UPDATE: corrected depth of nut catchment on the longer side, it was just a bit too far for a 15mm m3 to reach fully. Now no matter what offset is, using the same bolts should work
should work fairly well as is
so just print it out and put it in the spot where the proxxon micromot holder is. Word of caution thread may not print very well at layer heights above .3 (mine was at this point, they are functional but only one strand thick in places)
Screw onto the end of the dremel and follow the instructions for the use of the little bolt hobbit
If it don't screw on properly, you will need to play around with the settings in the scad to get it just right (threadRad is the main one to adjust). Or you screwed in teh m3 bolts too far and they are fouling the thread
UPDATE: so I've just hobbed teh first bolt with it and came out really well, thing of note is the dremel has 2 grooves in the thread that go about halfway down A 15mm m3 just fits in it, so you can screw it on the dremel and tighten the m3s past the nuts and into the dremel and it can't come loose.
