Creality Ender 3 filament adapter

Filament adapters to create the least amount of drag possible on the factory filament holder.

**THIS WILL ONLY WORK ON THE TOP MOUNT SPOOL HOLDER WITH THE THREADED NUT ON BOTH ENDS. THE NEW TOP MOUNT SPOOL HOLDER WITH THE NUT ONLY ON ONE END WILL REQUIRE A DIFFERENT DESIGN**

There are three size outer diameters, they are slightly undersized 1mm from spool measurements, so that they fit inside the spool nicely.

49mm, 54mm, and 56mm

**update

I added a 2mm washer to the file list.
