Summary

Self-priming drill pump with handle, adaptors to fit standard ¾" GHT garden hose threads, and slinger with cover and direct and drain fluid leaks away from drill.

All parts printed in PLA, except the Rotor Vanes and the Slinger, printed in TPU
Unless your printer handles TPU better than mine, I would recommend printing the 10 vanes individually.
Drill shaft was made by cutting the end off of a ¼" shaft spade drill bit, approx. 3-1/2" inches long, holes sized accordingly.
Use CA glue to secure shaft to Vane Hub, and Slinger cover to the back off the Main Housing, drain facing down.
Epoxy Hose Adaptors to Main Housing (if needed)
4x M4x30 bolts and nuts in top 4 bolt holes to secure Cover to Main Housing, and 2x M4x40 bolts to secure Handle and Cover to Housing through the bottom 2 holes
Rotation direction does not matter, but pick a rotation direction to bias the vanes when installing and stick with that, then the rotation of the hub goes from the outlet side towards the inlet side.
