Low Profile 'Doorknob" Latch

Made this for a utility door in a small room so there wouldn't be an intrusive knob or handle.

I tried printing the lever on it's end so it would come out cleaner, but it wasn't strong enough.
(Would be easy to use a metal dowel or something instead, then print 2 of the backs and glue it into place, but printing on it's side seems to have made it strong enough)

The screw holes aren't threaded, so you have to thread them using the screws.
(I recommend doing so before assembly)

Hardware:
4x 16mm M5 Screws
(1.375" x #10 Should work too)

1x 1.375" 23/64 Spring
(9mm x 35mm should also work, but might not snap into place making assembly a little harder)

The levers are a little longer than I'd like, but I figured it's easier to cut them down than to get them to grow.
