Endcap for the spool holder tube found on Ender 3's and similar printers.

I made it to stop the spools from falling while using the spool rollers made by @DropBOB_Designs (https://www.thingiverse.com/thing:4801992). Position the rollers as close to the bracket that attaches them to the extrusion so the spool can't go over the endcap. It should stay put with friction alone.

In customizer you can customize the inner diameter to match the inner diameter of your holder tube and the outer diameter to set how wide you want the endcap to be.
