Spool Holder End

This is an add-on I made for the "Monoprice Mini Delta Spool Holder w/ Bearings" by dontbesalty found here: https://www.thingiverse.com/thing:3573692

When I first used the mod I was worried the spool might slip off the spool holder since the mod lifts the spool above the end piece that would prevent the spool from slipping off. So I took dontbesalty's design and modded it to create an end piece that can be slipped on and off of the spool end easily but also prevents the spool from falling off. I'm not saying the spool will fall off with dontbesalty's mod but I like being careful. It's a simple print and doesn't need any supports.
