D-Bot and C-Bot Differences
1) The lead screws and Z motors were moved forward to better lift the print bed from its center of gravity rather than use a fully cantilevered print bed.
2) Increased printable Z height to 330mm (~13")
3) Use of 20mm rails for the bottom sections to save cost and reduce bulk.
4) Various adjustments of printable parts, either to add plastic where it seemed like more rigidity was needed or to subtract plastic where it was not needed.
5) Accessories such as a simplified spool holder a cable chain for bed wiring
6) Relocated endstop mounting to maximize Y travel and utilize default homing scheme.
7) Overall reduction in cost compared to the original bill of materials (2$ square nuts vs 40$ Tnuts, etc.)
