Gotta make it work


I am working on a project and bought this old Gilson Minipuls Peristaltic pump real cheap. It was dented and being sold "for parts." The motor worked and it came with a pump head (not pictured.) But the plastic part that transfers the torque was broken in the sale pics, and missing in the package. After some metrology and CAD, I have a new part printed and tested. This part was printed in PLA, which will work for testing, but I will be printing it in carbon filled nylon for production. The manual says it needs grease during use, so a oil-resistant, low friction nylon might work.

Materials and methods

Print as strong as possible. No support needed as oriented.
