Hi-Tech All-You-Need modified top with "stonecatcher" wall

I make intarsia, which is a mosaic of different semiprecious gem materials normally in the form of a cabochon. Somethings these stones have sharp corners, and sometimes when polishing them on a flat lap, I have had them sometimes go flying off the dop stick and end up somewhere in my studio. To prevent this I added a "stone-catcher" wall. There is also a hole for a water drip delivery tube. It is to be printed in 3 parts and epoxied together. I also have covered with a thin layer of waterproofing.
