Overview:
I wanted a mini 1/4" hex drive ratchet set at work for confined areas where large tools don't fit. There is a great set by Wadsworth, but $160 was a too pricey. So I picked up a $15 VIM Tools HBR3 and some hex drive bits from Menards. That way I could have every bit I needed and none that I don't. A quick trip to Solidworks, and some printing time later and I have the perfect mini ratchet set for my needs.
Native Solidworks file included, as well as conversions to Step, X_T, Fusion360, STL, and 3MF. Hopefully these files can be useful for you, or inspire your own designs.
Materials:
I printed my 3D Printed Parts in red Inland PLA.
