I bought these little submersible water pumps for a project. Unfortunately the liquid I was pumping (water with an anti-fungal, anti-bacterial additive) caused the acrylic(?) pump cover to crack and fail.
I ended up using using a different pump for the project, but I decided to design and print a replacement part for the failed one, mostly just for CAD practice.
The replacement part functions well with regular water. I printed in PLA. I don't know the longevity of PLA submerged in water.
Here's a short demo video. https://youtu.be/LJN6VxBYWdM
Notes:
To thread the part on to the motor of the pump, I needed to scale this to 104% in the X and Y directions in Cura. You may need to make a similar adjustment. Flip it over so the threads are up before slicing. You need supports, from the build plate only. I printed with
100% infill mainly to minimize areas when water would accumulate.
