Creality Ender 3 Double Spool Mount

Recently I printed with two differnent filaments and swapped them midprint (https://www.thingiverse.com/thing:4910567). When hotswapping filaments I found it helpful to have the secound spool prepared and ready to load at hand. I took Zolkoras great idea and design, but I cut the top-rim off so that supports are only necessary from buildplate and printed a plug instead.

Beside this I discovered, that there was to much clearance, the original nut was a little bit tighter. For half a second I considered to print it slightly scaled again, but then I just printed a 0.6 mm washer/spacer instead.
