Snap Fastener

I was working on a garment and shoes for my dog to be prepared for the snow and ice that annually appears in the area I live. It's a global warming thing. Anyway, I couldn't find a simple snap fastener to 3d print so I decided to design one. This is printed on my Kobra 3 Combo using PETG. Nozzle temp is 230 and bed temp is 70. No supports are required. This can be scaled larger or smaller in Anycubic Slicer Next. I will be test printing this in TPU to see how a more flexible filament would work with this As soon as the printer gets done printing the test boot for my dog is finished. UPdate: I just printed this in TPU. It turned out real nice. If you just want a snap fastener for normal duty the TPU will work fine. If you need a bit more strength then use PETG etc.
