40mm Medallion/Coin Jig for GweikeCloud G2 Lasers

This is a jig for holding 40mm diameter medallion/coin blanks specifically designed for the GweikeCloud G20 machines. Though, it may work in other machines as well with the same hole spacing. It is intended to be screwed into the machine's base with 4 M5 - 8mm socket head cap screws. The opening is 40.25mm, so the medallion/coin should snap into place and be held quite tightly. It is designed to hold the material against the machine base so that heat will be quickly dissipated during the engraving process vs. other jigs that hold medallions/coins aloft. Even so, I suggest printing with a higher heat filament like PETG or better.
