I created this spacer to elevate the Ikea Brusali Shoe Cabinet. I needed to raise the cabinet about 3.6cm to allow the cabinet back surface to clear my wall base trim. With this spacer, the cabinet back rests fully against the wall. As designed by Ikea, the Brusali shoe cabinet tolerates a wall base trim that is shorter than my wall base trim.
Use glue or double-sided tape to hold the spacer against the foot that comes with the cabinet. The weight of the cabinet rests on the spacers. There are two spacers per cabinet. There is no difference between the left and right spacer.
I printed this in PLA with 35% infill, no supports. To customize the height of the spacer, you may use a slicer to scale this model along the z-axis.
