Insert small, 5 x 10 x 2 mm magnet, from Prusa MK3S sensor system, into pocket right of armature

Bunny Science needs only a single magnet. Magnet pulls bearing into filament path. Filament pushes bearing out of path and swings armature. Interruptor fin triggers MK3S IR filament module (to be installed later)

Magnet strongly attracts bearing making armature less prone to rattling during accelerations.

When using the single filament armature, you will also place one MR63ZZ Miniature Steel Bearing as a spacer on the idler door hinge screw.
