Hidden wall mount tapered dovetail

thingiverse

This component was created to replace a picture hanger and nail where my key hook hangs. The original hanger always pivoted when the weight wasn't evenly distributed and was easily knocked off the nail. This design will fit tightly, resolving that problem. The dovetail is tapered so it can be printed with minimal calibration requirements; it should still fit together regardless of slight size variations. I designed the dovetail to be printable in either a flat or upright orientation. Theoretically, the strength should be superior if printed vertically. For optimal results when printing vertically, the female dovetail should have the narrower side of the taper on the print bed and the male part the opposite. This ensures that the raised edge formed by the first layer won't cause interference. I printed this component in PETG; however, the detail would have been better with PLA, and I'm confident PLA would be quite functional for indoor use.
