Prints without support. There are two versions of the Stl Right-Windowholder is for windows with the hinge right. You just need to gently stick a knive between both parts to make it move freely. I included the fusion 360 file so you can modify it. I would recommend to print it with PETG so it won't deform in the sun. Plese note that it isn't designed to hold an window open at an 90d. angle.
