This is a improved version of the Prusa i3 3D Printer.

see http://reprap.org/wiki/Prusa_i3.

• Aluminium Frame has now a Y-Plate with 3 points to attach the Heatbed ( compatible with MK2a + MK2b Heatbed )
• Aluminium Frame had some little bugs + the milling time has decreased to 50%.
• x-motor-end has been moved 5mm outwards to don't bump into the RAMPS electronics board.
• teeth profile on the x-carriage has been seperated to print better ( teeth part is printed with a 0.3mm nozzle layer height 0.2mm )
• y-beltholder has been improved to print faster
• addons for now a clamp-on spoolholder
• extruder is addapted from EiNSTeiN variant, with some improvements for printing and usage, added fanholder ( there is still some work to do )
