Coin Ring Center Punches (1 Euro ,2 Euro, US Quarter, US Half Dollar, US Nickel, US Penny)

thingiverse

Here are some center punches to create coin rings for the 2 Euro, 1 Euro, US Half Dollar, US Quarter, US Nickel, and US Penny coins. Each center should be precisely drilled according to the dimension marked on the punch. The holder securely centers the coins, allowing you to mark the exact center of each coin with precision - a challenging task indeed. You may notice that the coins have 0.1 mm of clearance around their edges; however, this can sometimes cause issues with print tightness, so be prepared to tweak your printer's settings if necessary. Fortunately, the inventor has included CAD files for easy reference and customization.
