I want a power drawbar for my mill, and the plan is to build it from the guts of an impact driver. First I need something to hold those guts, so in August 2023 I designed a housing for them.
It's a fairly complicated part, with stepped pockets and slots sized for the motor, gear and anvil of the disassembled driver. It was a sort of fun modeling job.
I printed it the next morning, and it turned out to be a pretty good fit.
This is as far as I've gotten - the project has stalled, but I hope to pick it up again at some point.
