End caps for filament roller

Just some end caps to fit a 22mm plastic or metal pipe for the "Filler - The Customizable Filament Holder that fills your printer! " so you don't have to print out the full roller again if the caps on the end break.

Use 100% infill for it all or use a supports blocker to give just the smaller nipple 100%. Print with supports because the bigger part is hollow.

I glued them into the tube as well just to make sure they stayed in after.
