Hot Wheels Track - Wall Mounted Booster

As a part of my ongoing obsession with building custom Hot Wheels tracks mounted to the wall, I designed this motor driven booster. 

The parts required to replicate as shown are:

• 2x type 130 mini DC motor (similar to these)
• 1x DC motor speed controller 
• foam tape 7/16" H x 3/4" W (weather stripping foam works pretty well, make sure the foam is not larger than 7/16" or 11.1 mm thick since there is not much clearance between the inner motor and the wall)
• screws to mount to wall (holes are 5mm diameter)

The quantity of printed parts needed are:

• 1x motor mount (printed flat will need some supports for inside the motor holes)
• 1x track connection (will need a small amount of supports to the build plate only)
• 2x driver (attaches to motor drive shaft, may need to be drilled out just a bit depending on your printer's tolerances. I should be a snug/press fit to avoid slipping on the shaft.)
• 1x speed controller box (print-in-place hinges and option for color change to show HW logo, I only just realized I should have blue and orange instead of green and silver)

The distance from track center to wall is 73mm. I've included a separate track mount that aligns with this offset (pink in photos).
