Ergonomic TPU grip for Porlex Mini

prusaprinters

the handle slot on my Porlex Mini silicone grip tore within a couple months, so I decided to try printing another with TPU. I realized I could make it a little more ergonomic for my large hands. This has a sort of triangular profile to nestle into the hands better, and retains the slot for handle storage.I printed this in generic 95A TPU. It's ok, but it can slide a bit too easily with light roasts. You can either print it in a grippier filament, like that fancy TPU with recycled tires, or do what I did and coat the inside with RTV silicone.I also had to bump up the extrusion to get the thin walls to fuse, otherwise it printed as two walls with a gap. That might be normal with TPU, I'm not very familiar with the material yet.
