Quick-change Wrench

thingiverse

This thing is a wrench that can be quickly changed for size or from Imperial to Metric. It is handy for light duty work. Two wheels are for the nuts that go with M2, M3, M4, M5, and M6 screws. The other two are for the nuts that go on Imperial #4, #6, #8, #10, and 1/4” screws. It has storage for a 1/4” hex drive reversible bit with ball detent and a receiver for using that bit. I printed all parts with no supports oriented as shown in the screen shot from Cura. I used a 0.8mm nozzle and 0.2mm layer height. A picture of the hex drive bit I used is included. NOTE: Drill the hole in the wrench handle out with a 5/16" (0.313") bit for a nice fit with the shafts on the wrench wheels. https://youtu.be/fLpBZlg5hkE
