This is a fully functioning spring-loaded cabinet latch appropriate for standard kitchen cabinet size doors and smaller. I used it on a BBQ cabinet along with the Steampunk Hinge also on this site.
The springy bit is the flexing PVC 1/2 circle seen about mid-way; it is long lasting. For a finish I mixed acetone with copper powder and painted it on with a small brush. Once dry high gloss polishing with a brass dremel brush or softer tools is possible.
Printed in ABS at .3 mm resolution. Finish coated with acetone mixed with copper powder and then polished with dremel tools. Uses #6 screws to fasten or if scaled to 80% it will use #4 screws. With the copper powder I anticipate it will change colour and go green with humidity which is the desired effect. Or just paint it. Copper powder is on ebay. See the matching hinge.
