Hex to Rotary tool adapter

thingiverse

6/15/2019 1100 I don't like to get like to get out my rotary (craftsmen) tool and plug it in for a quick little thing. I don't always need 28,000 rpm when I have a few battery powered drills and screwdrivers. But I sometimes need a small grinding wheel. I also need more practice with fusion 360. I was going to do this in SAE but the grub/set screws (box seen in one photo) were in metric (45H ISO4029/DIN916 Cup point socket set screw thermal black coarse metric M4-.07mmX4mm) and they only sold them in boxes of 100. So..... It is obviously not a great solution with the grub screws, the shaft still rotates, <del>I am thinking more screws and thicker round part.</del> The first one pictured was printed upright with supports, a pain to get off. I re-printed rotated 180 no supports and it came out great (pictured with raft). I still had to use a 1/8th drill bit to bore out the shaft hole. Now 97 more grub/set screws (the box can be seen in one photo) to use in other designs. 6/15/2019 1215 <del>added a slightly beefier version with a larger shaft hole and then an even beefier version of that that can have 4 grub screws.</del> 1325 Don't know what happened those hex shafts are way off, I'm trying one of them again but going scale 103% on XY. 1336 Was using inscribed polygon when I meant to us circumscribed. 1451 V6 is up think I got it best it is going to get, the hex shaft is now slightly oversized 7mm as opposed to 6.3mm of a PH2 bit (compensating for PLA shrinking). Enjoy!
