Couch wall distancer

I wanted to stop my Ikea Vimle couch from always going against the wall in the back, so I created this spacer to go around the foot of the couch, and keep a minimum distance.

Included the SCAD file so anyone can customize it and print to their own needs, if they have other dimensions.

Dimensions are in mm:

Width: 74mm
Height: 50mm
Length: 90mm

Foot radius: 35mm

Space for the trim: 20x20
