This is an all metal build using OpenBuilds V-Slot linear rails to produce a high quality and cost effective 3D printer. The printer is designed to be scalable for your desired build area and can utilize high quality hotends with 16mm groove mounts such as E3D.

Core XY, sensor-less homing, integrated camera, touch screen, pi, 32-bit controller, fast, quiet, beautiful prints. 300 x 300 x any build volume. Just change out the Z lead screws, rods, and four pillars. Total BOM around $700 USD. Build time around 6 hours.

Stronger frame for Prusa i3 MK2 / MK2s / MK2.5 3D printer

A blend of modular aluminum and steel bracketry built to yield fine cuts in hardwood and aluminum. An open table with a shiftable pin-fixture concept will allow the operator to shift longer than Y-travel work-pieces, such as doors, along the Y-axis of the table.
