Pump Hand Drill for hex bits
thingiverse
I really like speedy777's pump drill design, but I have a bunch of hex bit attached drill bits that I'd love to use. The knob at the top also didn't print well on my machine, so I remixed it to work with a 5mm x 16mm x 5mm bearing that I bought in bulk from Amazon. To ensure compatibility, I redesigned the parts so they won't fit with speedy's design. I print these bearings on a raft with no supports and they come out perfectly fine on my machines. Bearings used: Amico 10-Piece 625ZZ 5mm x 16mm x 5mm Shielded Deep Groove Radial Ball Bearing https://www.amazon.ca/gp/product/B00EDK5GIE/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
