My future DIL brought a broken plastic part, I scanned it and manufactured a (rough) replacement. It is not very accurate but a quick & dirty replacement.
If you expect a 1:1 copy, please give it a go yourself.
If you need something that's better then nothing, you can save a few minutes and just use this one.
I am not entirely sure which Ikea system this is from.
Sorry for the lack of pictures, its already put to use.
Print standing or better on the side to increase strenghth (but might require support material then, I printed it on a UP+)
