Spool Adapter : 51mm to 32mm Rod

If you use a filament box,the simplest rod to use is a 32mm (1 1/4") dowel. There's a few brands of filaments that I use, and the ID of the spool is about 51mm. So this is a spool adapter to make it mount properly onto the rod.

It fits eSun, CCTree and most of the spools I use. Measure the ID of your spool before printing it.
