Theta Core XY (Linear Rail Mix)

There are a lot of Core XY type printers like H-bot, D-Bot. I tried to make mine with constrains of my own. The cost of Rail MGN12 is higher than HGH20 here in INDIA. so I had designed it with HGH15C Block. 2020-Aluminium Profile is used as Infrastructure. I had also tried to have minimum Printed component. With 1605 Ball screw and PU Belt I think it will be rugged and robust built. Built Area will be greater than 450mmX450mm. Height will be greater than 350mm. Bolt Used are M3 for Idlers,M4 for
