Full Bear MK3 Z-Lineal Rails and Tr8x2 brass nut

thingiverse

I have already successfully tested this variant with the Tr8x2 brass nut, but I had more noise on the Z axis because my spindles are not 100% straight. It's up to you whether or not to use it, but for me, I prefer the POM mother. The dimensions of the Tr8x2 brass nut: Small diameter is Ø10mm, with an upper large diameter of Ø22 and a thickness of 4mm, featuring a 16mm hole spacing to screw on. See project https://www.thingiverse.com/thing:3849454 X-Axis (End) Two MGN12H linear blocks are used. Eight M3x6mm Cylinderhead screws secure the assembly. Eight M3x8mm Cylinderhead screws reinforce the structure. Eight M3 Square nuts provide additional stability. Z-Axis Two MGN12 linear guides, each 310mm long, support the axis. Twenty-four M3x8mm Cylinderhead screws are used to fasten the guide. Twenty-four M3 T-nuts secure the screw in place. Four M5x10mm low-profile screws (Z_top) complete the assembly.
