Adjustable Dumbell Handle for 1" or 2" weights

This model has 3 main parts, but one of them is optional depending on your weight selection. For one handle, you will need to print 2x of the screws, 1x handle and as many of the centering rings as you need. I have tested it with 50 pounds (25 on each side, shown in the picture) and had no issues so far. I printed this in Carbon Fiber PETG, with a .6 nozzle.

Use at your own risk.
