Ikea RÄCKA rod sliding bushing/sleeve

Curtains with fabric tabs hung on the Ikea RÄCKA curtain rod are very difficult to slide due to the expansion at the joint of the rod (when using its adjustable length). A bushing like the one from this model can significantly reduce this problem.

There are two models. You can print the whole thing. However I mostly tested the first version with glued ring (afterwards).
