Spacer for masterspool adapter for Sunlu refill spools

The adapter from Jens238 works great. Fiberlogy masterspool refills are smaller (only 700 grams) and less wide, so i made a spacer. 

Print it with standard settings: 3 walls and 20% infill. 

Stick it to the preferred side of the spool (which doesn't matter, i prefer the lid) with double sided tape. 

It's more of an extra spacer, to fit 750g masterspool refills snugly
