I used https://www.thingiverse.com/thing:2343318 Praying Hands Fridge Magnet by mb20music as an insert (CC, Attribution, Share Alike), and added the border and infill disc in tinkercad.

At 100% size I am still getting some skipping on the finger outlines on the hands, so try 110% or so. I think the lines are just too thin to print using a 0.4mm nozzle. Should be fine with a 0.2mm though.

Unfortunately I gave all I had printed and painted to the Cleric in our D&D group. As soon as we play again I will take pics and post.

This is my first upload. Feedback appreciated
