This is a simple spacer to go behind ringed curtain tops to get correct spacing when Curtains are open. This is a thing my wife asked me to make, and the results were pretty good. I have included pictures of the Curtains in question, also a STEP file produced from fusion 360 for remixes. I made this 70mm long and to fit a 28mm curtain pole. Every pole would be different as the spacing for the curtain loops will be also, so expect to have to alter to suit your needs. Enjoy the brownie points!!!!
