Hi all! (=
This is my 3-wheeled mount for Z-axis. So you can save 1 wheel instead use original 4-wheel. Also by 3 wheel much easier calibrate. In files you can see two versions.
First version has 2 parts (Z_Wheel3_Guide-Part1 and Z_Wheel3Guide-Part2...) where part 2 can be used with tensioner or eccentric.
Second version (Z_Wheel3_Guidev2...) is more stronger and prefered by me. I recommend to use this version. But there version only with tensioner. I like tensioner there, it so useful and easy.
P'S: On Re-D-Bot and D-Bot analogs, used Micro V Wheels.
For tensioner you will need one M5*15 (or some M5 suitable length) and one M5 nut.
+1 mm to outside, for more easy assembly
