Prusa BOX - Modular, Scalable, Open Source 3D Printer

Here's my remixed I3 design that I've dubbed the Prusa BOX. By using 1" T-slot extrusions and boxing the frame at the front, the Prusa BOX design is much more rigid than a standard I3 and enables easy, convenient transport. The additional extrusion space allows more mounting points for electronics, power supplies and other add-ons, eliminating the need for umbilical-cord style control boxes. This design allows the printer to be safety rotated on it's side or upside down for maintenance/swapping parts, and can print in any orientation for style points.


The goal of this design is to provide a guide for those wishing to upgrade their current Prusa/I3 style printer onto a new frame, or scratch build a Prusa BOX. It scales in build volume easily based on the length of extrusions and linear shafting used, and will be better suited to 12"+ build volumes than a standard U frame. I'll provide native CAD files for all the parts and assembly files for the most popular frame sizes, 8x8
