Ikea Plug for Curtain Rail system "Kvartal"

thingiverse

This is a replacement plug for Ikea Kvartal curtain-rail system. I've designed this using OnShape and the link is this if you want to work with my source if you need some adjustements: https://cad.onshape.com/documents/26f6ee1a9e3d259315dbb71b/w/7f775dc11c8bdc5b90be17ad/e/9e87e8c9389536688fd73604 But I can assure you that this piece fit perfectly. There is only an issue about the threaded hole: don't use supports, even if the threading is not correct, the bolt screws applying a little force. This is my first object I design on OnShape
