Nut on screw for busy board

Nut on screw for busy board, also known as an activity or Montessori board.

The nut can be rotated with ease. Mounts are tighter.

Mounts are screwed on. The screw has the right length so they face the same direction.

I have printed the nut and the mounts with a 0.2mm layer height. The screw with a 0.15mm layer height for looks.
