A rock climbing pinch hold I made in fusion360. Modeled for a 3/8 inch bolt that is commonly used for climbing holds. Also has a hole for a 2-inch wood screw to prevent spinning.
Use this file responsibly. If this is used right off the printer make sure you use many walls in your print and chose the strongest infill you can. Don't cheap out when an injury is at risk!!! This would be a good model to print and make a silicone mold out of, then cast the useable hold with resin or like materials.
With that said, have fun with it. Please post any pictures if you make it! Thanks.
