Easy to print and very useful! Use ASA or PETG if using outdoors, otherwise PLA is fine.

My cat was continuously jumping up on my air filter and pressing all of the controls to boot. I decided a non-drastic way to deter her was to create these little safe spikes to keep her from jumping up on to surfaces I'd rather she didn't. I have offered three different sizes, and solid fill the base for integrity.

I found my curious cat was fascinated by the speakers on my soundbar, and started to claw at them. This simple cover doesn't impede the sound at all, and keeps the speakers themselves very safe.
