Monolith grinder portafilter clip

I've had trouble with the portafilter falling out of the grinder, too. Whenever I place the beans in the grinder and turn it on, I step away to get some milk, but sometimes the portafilter starts vibrating so much that it rotates completely around. This only happens occasionally, but one time it happened to me, the portafilter rotated enough that it fell out of the grinder and spilled all over the grounds. To put my mind at ease, I wanted a way to prevent this from happening again. With plenty of time on my hands now that I'm stuck at home, and having a 3D printer at home, I decided to create a little lip for the portafilter. This would ensure it stays in place while grinding. Here's what I came up with, printed in PETG.
