I've broken the hook 3 times, so I added a screw

remixed doorstop hook!

LoboCNC's doorstop is very clever, but I've broken 3 of the hooks, so far—by forgetting that the doorstop was in place, and trying to close the door.

according to KISS principles, rather than designing a complicated pistoning hook with a spring, I decided to try simply reinforcing it, first.  we'll see how long I go before breaking this one.

parts

I used an m3x30, coarse threaded, cap head screw, and a standard washer, but whatever you have on hand that's close enough will probably work.

printing

I used 5% infill, but 6 walls, to give the screw more to work with.  the hole flattened considerably in printing, and—rather than making it oval, or something—I just made the counterbore large enough to still accommodate the m3 washer.  the screw hole was a bit tight, but it was still easy to drive the screw in.

for convenience, I'm including the collateral stl files from LoboCNC's original model, but please go give the original a heart and a download.
