Black Cat Resources "The Cat Fish pump" (Cana AR-1 Alternative):

I designed this bracket for myself but wanted to share it with everyone so you can build one of these as well.

This pump setup is based off a design from Black Cat Resources and from a video from Truth & Freedom Ministry. They really got this ball rolling on making a more budget-conscious Cana AR-1 alternative.

The main thing I wanted to incorporate into this design was u-bolts to make a "cage" to protect the pump.

 

I am no 3D modeler; I made this on TinkerCAD, and if someone can refine this, please do.

This design is free and meant to be free for all to use.

 

The print settings I used were .2 Layer height, 100% gyroid infill, 6 walls. No brim needed, but print with tree supports.

Made with a bit of wiggle room for out-of-spec printers. I used PLA+, but it may not hold up to extreme heat.
