T-joint IKEA Räcka Tripod coupler

Needed an easy backdrop and I already had a bunch of cheap amazon photography tripods. So I picked up a thin extending IKEA Räcka curtain rail (part no. 10217160) and drew up this T-joint to screw it onto a tripod. 
These tripods normally have a ¼" screw on top, which easily screws into the recess in the joint to lock it in place.

Printed in PETG, standing up straight to allow the least amount of supports (needs a tiny bit on the bottom to ensure adhesion). Warning: this is a pretty tight fit!
