Self-adhesive cable tie mounts
thingiverse
Walking through a Dollar Tree store, I spotted these pre-cut double-sided sticky tape rolls for $1. So I came up with a drawing. You can buy self adhesive zip tie mounts for $7 - 100 pieces, but save a few cents by making your own. The mount measures roughly 1/2" (12.7mm) x 3/4" (19.05mm) x .150" (3.81mm) tall. I made the width of the openings (.220") large enough that 3/16" wide zip-ties can fit though easily.
