Yo Curtain! stay where you are! I have printed these in 9x batches, printed a 9x set in PETG and another 9x set in PLA. actually material did not matter a lot. you can print it in any material you have. stick it into cornice, twist 90 degrees, it will get stuck there. stops the curtain and prevents it to be derailed unintentionally. easy to print, easy to put in place, easy to remove.
