Welded frame prusa
thingiverse
This is my version of i3 printer. The main goal was strong metal frame and as simple as possible construction. Frame is welded from 20x20 square steel tube, Y axis is Anet A8 stile, because it is simplest to make, and X and Z axes are fully compatible with Prusa MK2. You need only z-axis-bottom, z-axis-top, y-motor, y-idler, y-holder, y-endstop and footstep files, all other parts are Prusa MK2 and Anet A8 compatible and freely available in the web. The lengths of the tubes: 2pcs x 365mm sides 2pcs x 302mm (front, back) 1pcs x 342mm (top) 2pcs x 380mm (z axis) The lengths of the smooth rods are same as Prusa MK2. A year ago when I made the printer I had difficulties to find good linear bearings, that's why i created some parts with radial bearings. https://www.thingiverse.com/thing:3715169 https://www.thingiverse.com/thing:3878405 That is a cover for RAMPS which match to the frame. https://www.thingiverse.com/thing:3871826 And video. https://www.youtube.com/watch?v=Qben1WrKGkA
