Ender 3 Dual Spool Adapter/Small Diameter Adapter

I purchased a spool of AMZ3D PLA and the hole in the spool was too small to fit on the stock Ender 3 spool holder. I designed this part to be able to mount smaller diameter hole spools on the opposite side of the stock spool holder. As an added benefit I can now have 2 spools loaded at the same time for dual color prints. This was my first design.
