A parametric, highly material efficient, spacer. You can customize the spacer to your needs by clicking the green Customize button, right next to the “Open” button!

When your furniture drawer has just that extra few annoying millimeters of space that makes your gridfinity base slide around. Excellent for use with Gridfinity bases and IKEA furniture.

The holes in the design also allow the model to be bent, which allows you some margin on hard to measure builds.
