End support for Ikea roller blind

youmagine

A replacement end trunnion for Ikea roller blinds. This part fits into the end without a chain attached. It comes with an integrated file support that forms a wall around the part, greatly reducing the need for additional material and print time. After printing, simply remove the wall to use the part as intended. If the hub shrinks during the printing process, making it too small to fit properly, wrap several turns of tape around it before installation.
