The Goal here is to create a lightweight, minimal x carriage. the carriage will have a large central opening to facilitate various hot end designs, and provide enough room to insulate the hot end.
I find the default Sells carriage too bulky and confining. I also hate that the mounting points are above the rails, which means the whole carriage has to be disassembeled if you want to get to the extruder. It also has a lot of mass, and much of the structure is bellow the rails, putting it close to the hot end and risking warping from the heat plume.
here's what i came up with:
Those m4-40 bolts are all that i had that would reach.
In order to make construction easier, i didn't oppose the bearing by 120 degrees each, instead opting for a 0, 90, 210 degree config.
A side effect of this configuration is that the carriage can clip on and off of the rails easily with minimal disassembly. only the undercarriage bearing on the other rail has to be loosened.
here are some pictures of the individual parts:
