Ender 3 Spool Spacer

Couldn't find anything here that was simple to keep my side mounted spool from creeping close to my Ender 3's X stepper motor. So did this quick design and print to fill the excessive gap. It's not enough to tighten the spool down, but keeps the roll from shifting so much across the length of the spool.

Spins on the spool as necessary, but still easy enough to remove and won't just fall off.

I'm happy now!
