IKEA RÄCKA Curtain Rod Holder

This is an IKEA RÄCKA curtain rod holder if you have a frame windows like I do.

This rod holder comes in two different parts; one is 16mm and one is 19mm, as the RÄCKA rod has two different diameters. Print each of these. 

The hole on the side will allow you to place a heating-insert to add a bolt to lock the rod if you wish, but it's not mandatory (I didn't use it).
