About this 3D model

This is a bracket for a pneumatic screen door closer. It will likely replace many brands/models. I've attached step and fusion 360 files to make it easy to modify. I modeled this to match the original (broken) bracket on my door closer as shown here: You may be able to rotate the part 60 degrees onto the rear face (as shown) and print without supports, but it's a relatively small contact area so you may want a brim if you struggle with bed adhesion. I printed mine in PETG with a 0.4mm nozzle and 0.2 mm layer heights. I don't think the tolerances are very tight for most door closers so just use whatever makes you happy.
