Printed door latch for printer enclosure door

thingiverse

Requires an 8mm hole, center of the hole about 8mm from the panel edge that you're trying to latch to. I think I made versions for thicknesses of plastic that are nominally 3/16" and 1/4". I've included solid model files for user adjustment for panel thickness. The screw is M3mm x 12mm or 14mm. You'll probably need to drill out the holes. The knob needs a hole for clearance, the hook part needs hole for slight compression fit on the screw. Solid model files provided for user to adjust, otherwise the hook part can be scaled up in Z. Alibre for those with Alibre & Cubify software, and STEP for everyone else. The amber sample is printed out of 3DXTech Ultem 1010, the white sample is 3DXTech polycarbonate. You can use any plastic you like, something with a little bit of flex is better than too stiff. It's worth experimenting. I suggest one for each outer corner of the door for best sealing but one at the middle of the outer edge is decent.
