I use one of these... https://www.banggood.com/12-24V-Lathe-Press-Motor-with-Drill-Chuck-and-Mounting-Bracket-p-1022337.html?rmmds=myorder&cur_warehouse=CN ...in a 3 part 3D printed grip enclosure. It runs off anything between 12v up to 26v, so 3S-6S. Of course, the higher the voltage, the better the speed, but generally, the torque is pretty good even on a 3s with a simple on-off flip switch at the back. I printed it in PLA, which I didn't expect to last long if the motor got hot, but it proved sturdy enough to last and hasn't shown any signs of breakage so far. Even the most basic printer should be able to make this. This has been a trusted and useful companion out in the field and on the benchtop, and I expect it'll still be around for many moons to come.
