Mushroom Pegs

Designed using FreeCAD, these were purpose built to support a cheap projector screen on the wall. The screen has grommets and came with hooks and double-sided tape. Nearly without fail, at least one hook would pop off the wall every day and need to be re-stuck. Never again!

The Mushroom Pegs have a cap diameter of 18mm and a stem diameter between 10.5mm and 13mm. Total height is 10mm (5mm stem/5mm cap). They fit the #8 screws that came with my drywall anchors.

This may not be unique to the marketplace. Honestly, I didn't even search for existing solutions. I had a problem and decided it was a perfect opportunity for my first design attempt.
