Had a little ORA gonipora frag that was constantly being pushed around in the sand. A few minutes with OnShape, and I had a new thing to try...
Worked out great. Holds a 1/2" frag plug. Cover the base in sand, and it pretty much disappears. I used a light grey PETG, 100% infill, of course. So far, it's doing the job.
