Strong Drawing Machine XY base for external rails
thingiverse
This is an enhanced version of the Drawbot Drawing Machine XY carriage base sourced from www.thingiverse.com/thing:1517211 (and its derivatives). This modification significantly strengthens the base, increasing its resistance to bending when using larger plot sizes and rods exceeding A4 dimensions. The design enables the XY carriage to float on external C rails mounted along the sides of a 42x42mm wooden frame. On top of this wood lies styrene I-beams that support 19mm convex drawer slider wheels attached via M4 screws. One such wheel is connected to each bottom side of the carriage, secured with a screw hole manually drilled at the location of each former linear bearing.
