Screen Door Latch
thingiverse
I have a handle 'lock' on my screen door (the type that slides up and down) and it broke years ago. My dog recently learned to open the screen door so I had to replace it. Was about to head to the hardware store and then thought I'd try to print one. I looked around but didn't see anything that looked like it would work, so I grabbed the calipers and drew it up. Printed with PETG on 100% infill for strength. I made a couple with the initial one and then while taking a picture thought the support could maybe be a little better so I did the V2 to move the angle piece to the edge of the arm. I'm sure PLA or PLA+ would be fine too.
