About this 3D model
Use 8mm Smooth Rod for Mini Kossel , instead using Rail. Fit for 2020 frame. A little modify for mming1106. http://www.thingiverse.com/thing:335982/#files For mming106 version , the 8mm rod can be completely pass though. My version is for install at the bottom of the 8mm rod and fix the height. For each tower , you should need : 1) 8mm rod x 2 (46cm long) 2) LM8UU x 2 2) top printed parts x 1 (8mm_Axis_mount2.STL , from mming1106 version) 3) bottom printed parts x1 (8mm_Axis_mount3.STL attach in this thing) 4) Linear Bearing Mount printed parts x 1 (lm8uu_mount.STL , from mming1106)
