Modular Carriage for 40x20 inversion kit

I liked the idea of the original carriage but thought it was weird that all the weight rode on one wheel. These pieces are basically just new attachment points for the belt and limit switch so the whole thing can be flipped over. With the added thickness, the two top wheels require 45mm screws and the bottom still uses a 40mm.
