On Sunday my wife started the garbage disposal and it went bang. It turns out it swallowed a small Pyrex mixing glass. When it shattered it jammed everything and we had to take it apart. So right after I drew a grate to keep large things out. I wanted 3 touch points and a spring-loaded design. I didn’t spend any time planning it, I just started drawing. It took like 10 minutes. It turned out looking awesome and fitting perfect. All on a Sunday night. That’s a great example of a 3D printer being practical and handy.
