3Drag / K8200 redesign sketch, prusa-like design

thingiverse

I own a 3Drag, and there are some things that I hate in this printer: with a 3 mm glass on the print bed, the X axis weighs 1.7 kilograms! the printer shakes a lot while making fast accelerations on the X axis no belt tensioners only one threaded rod on one side the back of the bed is not insulated non-standard hole spacing on the extruder mount (an E3D hotend is the best upgrade for this printer IMHO) default extruder can't handle flexible filaments every M8 threaded rod I tried for the Z axis is too much wobbly, even the stainless steel ones. This is still a work in progess! This is only a sketch: sorry, there's nothing you can print straight away. I think I will start this project again from scratch, but with a Mendel90 frame instead. I'm trying to make a design with lighter X / Y axis, like in the Prusa i3, but a little bit sturdier (all the smooth rods are 10 mm in diameter), using only components that can be easily found on eBay or similar.
