Hex to Rotary tool adapter

6/15/2019 1100 I dislike getting out my rotary tool and plugging it in for small tasks. I don't always need the full 28,000 rpm when I have battery-powered drills and screwdrivers available. However, sometimes a small grinding wheel is necessary. I also require more practice with Fusion 360. Initially, I planned to use SAE units but the grub/set screws were metric (45H ISO4029/DIN916 Cup point socket set screw thermal black coarse metric M4-.07mmX4mm) and only sold in boxes of 100. Therefore, it's not a great solution with the grub screws as the shaft still rotates. The first printed part was upright with supports, which proved to be a challenge to remove. I re-printed it rotated 180 degrees without supports and achieved better results (pictured with raft). Nevertheless, a 1/8th drill bit had to be used to bore out the shaft hole. Now, there are 97 more grub/set screws left for use in other designs. 6/15/2019 1215 A slightly beefier version was added with an enlarged shaft hole, followed by an even more substantial version that can accommodate four grub screws. 1325 I'm uncertain about what occurred, as the hex shafts are significantly off-scale. I'll attempt to use one again but will scale it up 103% on XY. 1336 I mistakenly used an inscribed polygon when I should have utilized a circumscribed polygon. 1451 The V6 is now complete; I think it's the best version it's going to get, with the hex shaft slightly oversized at 7mm as opposed to 6.3mm of a PH2 bit (compensating for PLA shrinkage).
