Mechanical SEQ shifter for Sim Racing

Mechanical Sequential Shifter Design
Clamps to your desk, and you can bind the up and down shifts to any two adjacent keys in racing games.

This is my first time designing something like this, so any feedback is welcome!

Materials Needed:
(4) 10mm x 22mm x 6mm bearings
(2) Agri-Fab 44566 springs
(Cut the bent ends off the springs, leaving as much spring as possible too ensure they function properly)
and some Superglue.
