The file 'Olympic Weight Plates To Standard Lift Bar Adapters (Customizable) 3D Printer Model' is (stl,scad) file type, size is 944.8KB.
Customizable adapters for using Olympic weight plates having 50mm (2-inch) holes on a standard 25mm (1-inch) weightlifting bar.
The "guard" is what I'm calling the larger-diameter disk that prevents the weights from slipping over the center part of the bar (the inner collar on a standard lift bar is likely less than the 2" diameter hole in the Olympic weights). An additional guard-only part should be placed on the outside of the weights as well, if your 1" collar is not large enough to keep the weights from coming off.
I selected plate sizes based on the width of my rubber-coated Olympic weights (2.5 lb, 5 lb, 10 lb, and 25 lb), but you can create your own customized sizes using the attached SCAD file.
Print with lots of perimeter layers and 100% infill for maximum strength -- and of course be careful!
