Look at V2 (http://www.thingiverse.com/thing:766843) for some sense of instructions. Haven't had time to print and try yet...I recommend to download (v3 all parts.rar) where all files are categorized and sorted.Added all source files (123 design) and rename some of the .stl files.Added files for 10mm rods on x.Added files for 12mm rods on all axes.Added two different belt tensioners one on the (X-Carriage) and the other one on (x z holder L). Might not work...Added a complete set of cable chains, the x one might collide with the filament and the filament spool probably needs to be moved to the left side.Changed the (extruder mount.stl) a bit and added holes for cable management for the extruder.And check out MichaelAngeles pictures and files.Pictures.Redesigned K8200 Y bearing holder for LM10UU or IGUS.Redesigned K8200 Y belt holder with GT2 belt tensioner.Redesigned K8200 Z Holder anti backlash for TR10x2 with 17mm nut.Still need to figure out how to attach the heatbed and support it. Maybe some mdf?. A K8200 or 3Drag and some extra screw, nuts and washers (m3, m4, m5, m8). M8 threaded rod about 50 cm to get 300 mm on z. Heatbed 200x300mm. 2x rods D 8mm, 10mm or 12mm, L about 450mm. Longer belts. Zip ties. Maybe Longer feets.2x Springs for the backlash on (z_holder_endstop.stl) and (z_holder.stl). Nema 17 stepper motor. M8 threaded rod. Couplers GT2 belts and pulleys.
