Furminator Handle

The Furminator pet brushes are really great. I've had this one for eight years or so. It still works, but the rubber handle was starting to fall apart.
I designed this simple replacement in Fusion 360 (source file is included). It's kind of basic (the end is open, and there aren't any finger ridges), but it works.

I printed this in TPU, using a 0.8mm nozzle and 0.5mm, but it should print fine with a standard 0.4mm nozzle and appropriate layer height.
I also used 10% infill and Slic3r's "gyroid" infill for maximum flex.
