This is the STL file for the Newmatter MOD-T Lockbars (aka Mod Skis). Early buyers of the printer will not have these, so Newmatter has provided the gcode to print these. However they did not provide stl files.

These files will allow you to print modt lockbars on any 3d printers, I printed mine on an ultimaker 2, which gives it a mirror like finish with better quality.
