The design is inspired by the triangular frame of the reprap Mendel, It will be heavier and more rigid to be able to mill plastic, engrave circuit board and print at high speed.
Differences compared to the standard Mendel :
vertical X axis to quickly change the tool (extruder or spindle)
M10 and M12 threaded rods instead of M8 for better frame stiffness
10mm smooth rods instead of 8mm for better axis stiffness
Precision doubling belt configuration inspired by Madkite's design : http://www.thingiverse.com/thing:8852
nema23 steppers for the X and Y axis instead of nema17
Each axis will be equipped with 4 printed linear bearings : http://www.thingiverse.com/thing:16946
I will also try to use steel cables instead of timed belts for X and Y axis.
All parts are printed with 0.2mm layer height.
Work in progress.
[edit]
I've uploaded the different parts on several "things" for more clarity :
