Hello to my first 3D Print Post ;) I have created a custom Stone Holder for the Work Sharp Precision Adjust. I created it so I could save some money and dont have to buy the expensive upgrade kit with finer diamond stones. I used cheap diamond Stones from Amazon. Also they are bigger and in my opinion are better to use. I simply removed the plastic base from the metal-diamondplate with a spatula. And used double sided tape to stick the plate to the print. I printed it out of PLA with 15% Infill. If your printer prints the hole too small I have included the Fusion360 file so you can adjust it. https://www.amazon.de/gp/product/B0CNGD15BF
