A fully parametric pin designed to mount items with a keyhole. Designed to top mount a power strip next to a 3D printer. Haven't tested for wall hanging, use at your own risk. 

Because of the minimal clearance between the top of the base and the bottom of the pin, I didn't design in any chamfer or fillet to self support the pin, so best results achieved by printing with supports “everywhere”.

A few parameters drive the design. 

  1. Base: the side length of the base, always square and always 3mm tall
  2. Shaft
    1. Diameter: shaftDia - the diameter of the column between the base and the pin
    2. Height: shaftHeight - distance between the top of the base and the bottom of the pin
  3. Pin
    1. Diameter: pinDia - diameter of the top section
    2. Height: pinHeight - height of the top section

The pictured print 3mf is included (a 2mm x 2mm shaft, and a 3mm x 3mm pin). I've also included the fusion archive, so do with the model as you want! I'd like to see your remixes, link them to this model.
