Additional materials needed:
- 4x M4x30 flathead screw to mount pump to motor
- 3x M3x5 sinkhead screw to mount rotor lid
- 3x 608Z bearing
Use M3 and M4 thread cutter to cut the threads in the rotor lid and pump housing bottom respectively. If wanted, I can also provide a version for threaded inserts to melt into the printed parts.
I used this with ptfe tubing 3mm outer diameter, 1mm inner diameter.
I printed this in PETG as it had less friction than PLA and with 30% infill.
