skinny carriage for wanhao gr2, compatible with zortrax m200/300, wanhao gr2, d6 and d6or+, cr2020 and all zortrax clone. the project stems from the need to lighten the original gantry of the gr2 whose original (complete) weight is about 850g, too much f have good accelerations and speed. Tests are very encouraging, considering the low weight (about 350g) complete with cooling, pcb+flat, hotend with heatsink and sherpa mini.. on klipper I increase accelerations and doubling the working speed.

I published mount for mini sherpa recently and you can find it here,

the recommended materials for this gantry are pc blend cf, pc-pbt, pc-pbt gf, pc-pbt cf, pps, pps cf. (6-top, 6bottom, 5 perimeter, 40%infill for all part), have to be strong!!
using this type of material I avoided using brass inserts and drew threads directly on the piece, this solution is not giving me any problems right now, I await your feedback
