Kossel carriage truck for smart pcb (2020 extrusion, v-rollers)

thingiverse

This is a remix of dc42's design. My carriage hat too much flex so i designed it much stronger and with MUCH smaller tolerances. Additionally this takes the 2.1mm thick carriage adaptors into account which are added for the smart effector. Attach V-Rollers with one washer only, no need for a nut. I noticed the screws had play in their hole and would bend slightly because of the long lever due to the long distance to the rollers. So tighter tolerances and a single washer should improve this. I suggest printing with PLA, as other matierials like ABS and PETG are much more flexible.
