IKEA Rationell compost spacer

The purpose of the spacer is to keep the compost paper bag away from the bottom of the plastic bin. 

Two versions are included, please use the two part split design if necessary to make it fit your build plate. Snap it together with a little superglue.

IKEA Rationell number: 201.525.06

Update: I have added a half-size version of the spacer/aerator. Print two of these and put them next to each other at the bottom of the bin. No glue or assembly needed, fits the build plate of a Prusa Mini.
