A wall mount that fits a typical magnifying lamp with a 0.5 in. / 12.7 mm mounting post that is 1.5 in. / 38.1 mm long.

I included two versions, one that is tilted away from the wall 30° (as shown in the photos), and one that is straight up and down. This second version is untested.

When folded, my wall lamp leans backward 30° so the tilted version is what I first designed and what is shown in photos. With this version, you may need to use a screw to keep the post from rotating, as the lamp will want to swing downward. The hole for the set screw is ~ 1/4 in. and ready for an SAE 5/16-18 tap or insert if desired. This may not be needed in the vertical (0°) version. I used a 5/16-18 bolt threaded directly into the PLA.

Overall dimensions: 4 in. tall x 2 in. deep x 1.5 in. wide.

Print instructions

Printer: Prusa I3 MK3S
Rafts: No
Supports: No
Resolution: 0.2
Infill: 20%
Filament: Prusament PLA

No supports needed when printed with the wall side down. Printed with 4 perimeters for added strength - this may not be needed. The above settings seem to work fine, and allow the lamp to extend fully horizontal without any signs of mount issues.

Takes ~32g of filament and 2 hrs to print on the Prusa I3 MK3S with the above settings.

Tap with 5/16 in.-18 tap, or use a 5/16-18 in. or similar coarse bolt, or threaded insert (optional)
