Kossel Alt - 20mm extrusion - 8mm smooth rods

thingiverse

I've been using my Prusa Air printer since over a year now and I have decided to try delta type printer. Kossel is a really great design but as I had some 8mm smooth rods and 20mm extrusion laying around I wanted to use them instead of precision rails.. I've found Zam's Kossel files but after printing them out I've noticed that belts are not aligned with the carriages. I had some older stepper motors probably from an old printer(?) with gt2 pulleys pressed on the shafts and I couldn't remove them.., anyway I thought that it would be better to have belts running exactly between the smooth rods.. So instead redesigning carriage I have redesigned frame.. Carriage was taken from here http://www.thingiverse.com/thing:30611 Dry test http://youtu.be/RXFzkHzH564 Enjoy! UPDATE: 01/02/2014 As it was noticed by Senormeow http://www.ohmpie.com/delta_printer/, the 8mm rods are not sturdy enough for this height. I will be uploading stl files for 10mm rods version soon which should help to make it more rigid. If you decide to use 8mm rods anyway then I would advice to use shorter extrusion lengths for the columns or lower top frame by 10-20cm. Bear in mind it's still work in progress ;), thanks Instructions for the frame use: 3 x 800mm - 20mm extrusion for columns for the top and bottom frames use either 9 x 300mm - 20mm extrusion or 3 x 300mm - 20mm and 3 x 300 20x40mm extrusion
