Impeller Enclosure

I had a friend with a flooded basement, so I was inspired to create a small, simple, round, and sleek water impeller and enclosure. PLA+ worked fine for this enclosure. The impeller will need to be a softer and more pliable filament such as TPU. I have tried printing multiple thin finned impellers with PLA and sadly had little success. I can move water through this unit, but not as well as a fitted rubber impeller. 

Make sure your print bed is clean and level with a good Z axis calibration, and you should be fine using normal settings without need of any extra adhesion settings. This prints fairly quickly and fits together quite snug. If you are not careful removing the lid after connecting these parts, you may end up breaking the lid.

The square-shaped impeller enclosure was a difficult print that I abandoned, but kept here in order to rework and maybe improve upon the idea. I felt this should be a free and accessible option to help someone. It's all a bit of work in progress.

I'll add the impeller designs that I have played with, but a softer more pliable filament is recommended for printing your impeller for this enclosure. The drill bit fitting I was using can be seen within the impeller design. It is a 6mm x 8mm rectangle fitting. I may redesign these impellers using two separate parts, an inner PLA fitting and an outer TPU layer. This was a fun experiment and a decent waste of time :)

Good luck and happy printing!
