Cap Plugs

A simple cap plug in sizes 1-3/8", 1-1/2", 1-5/8". I needed cap plugs, ordered some online. All were metric, and the steps in sizes left out the sizes I needed. I printed in PLA+ but if you want flexibility, you will probably need to use PETG or TPU. The small ends are a little smaller than the nominal size.
