FlexiSpot C7 Armrest Forward Backward Lock

Designed specifically for the FlexiSpot C7 armrest. It may work for other FlexiSpot chairs. The part locks the forward and backward motion of the arm rest. It does not lock the left to right rotation of the arm rest. This print will not work for the very back position (arm rest pushed as close to backrest as possible), but will work for all other positions
