A replacement part for the end trunnion of Ikea roller blinds. This is for the end without the chain.There is a file with integrated support (a wall around the part) that will save you a lot of support material and print time. After the print you just need to peel away the wall. The other one is just the part as it should come out.If the hub is too small due to shrinkage in the print process, just wrap a few turns of tape around it before inserting!
