This is a small sized sheetholder that can be attached to your Ikea Platsa cabinet by simply pressing it in the desired spot.
Print the part lying down with support in between the opening for the sheet. The support is a bit fiddly to remove in the tight spots, so i would recommend a small screwdriver or something similar.
Print one part mirrored, otherwise the design wont work.
