UPDATE: 2024-July-19. I posted an updated V3 step and stl. needed to provide a little more clearance as my hinge started sagging and needed to clear the screen cover
wanted a mount that extends the screen out 20mm more to give clearance for the clicky clack door.
sloped the top extension to account for any potential sag your door might have.
The author remixed this model.
added a slope to the top to avoid binding if your door sags
