Aetherdrift MTG "Start Your Engines" Tracker

This is my first CAD design. I saw someone else's idea for a tracker for the new Start Your Engines mechanic that looked like a manual gear shifter, which feels super thematic. This is my version of that idea, with hardware I was able to acquire from my local ace for about $1.50. Pardon the jenky quality of my 3d printer, the bed is somewhat warped. Feel free to remix or change things, this was literally my first CAD project for the sake of bringing some swag to my LGS sealed event.
