Masonic Keystone (Mark Master, U.S.)

thingiverse

UPDATE 2023-09-22: Updated keystone as follows: 1. Adjusted font size so letters fit perfectly within circle 2. Set markings on the keystone to be engraved, blending seamlessly with the design This project prints flawlessly! Apply a coat of primer first, then use Rustoleum stone paint for a light finish. Observers are convinced it's made from genuine stone! The .STL file is blank in the center, but post-print images show the final product featuring my personal touch. --- After searching for a customized Mark Master Mason keystone to suit my needs, I couldn't find one that met my expectations. A few minutes of tinkering on Tinkercad allowed me to create this personalized design. Feel free to modify it as you see fit – it resizes beautifully! If you need the Tinkercad file, just let me know and I'll be happy to share it with you. I hope you find this useful!
