Ender 3-SunLu Spool insert
Description
The center hole on the SunLu Filament spool was 73mm wide, but the spool holder on my Ender 3 was about 35-36mm wide. Some of my test prints the spool didn't seem to spin as easily as some of my other filament rolls that had a smaller diameter opening in the middle. I made this insert using OnShape as my first creation. It was pretty difficult to get onto the Ender 3 Spool holder, because of the lip on the 2 ends. I tweaked the design with V2 to include on with a 40mm opening in the middle. But I only printed the 36mm version so far. Need to do a few prints with it on there to see if it helps the spool spin more freely than without.
