Pump Hand Drill for hex bits

I liked speedy777's pump drill design, but I have a bunch of hex bit attached drill bits. I also found the knob at the top to not print well on my machine so I remixed it to work with a 5mm x 16mm x 5mm bearing that I had purchased a bunch of off of amazon. I redesigned the parts so they are not compatible with speedy's design.

I print it on a raft with no supports and it comes out quite nicely on my machines.

How to assemble the drill. It was probably obvious, but just in case.
