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

thingiverse

Here's my remixed i3 design that I've dubbed the Prusa BOX. By harnessing 1" T-slot extrusions and encasing the frame at the front, the Prusa BOX design is significantly sturdier than a standard i3 and enables effortless, convenient transport. The additional extrusion space allows for more mounting points for electronics, power supplies, and other add-ons, rendering umbilical-cord style control boxes obsolete. This design empowers users to safely rotate their printer on its side or upside down for maintenance/swapping parts, and enables printing in any orientation for aesthetic appeal. The primary objective of this design is to offer a guide for individuals seeking to upgrade their existing Prusa/i3-style printer onto a new frame, or build a Prusa BOX from scratch. It scales easily in build volume based on the length of extrusions and linear shafting used, making it more suitable for 12"+ build volumes than a standard U-frame. I will provide native CAD files for all parts and assembly files for the most popular frame sizes: 8x8x8", 8x10x10", 10x12x14", and 12x12x12". Most standard i3 hardware will fit this frame, allowing users to utilize their favorite Prusa X-axis and extruder system. I'm utilizing the Mk3-style X-axis with a slight adjustment to hold precision nuts and my own E3D Volcano MK3-style swapping extruder system. Auto bed leveling using a BL-Touch with this extruder is feasible, but any Z-axis homing solution is viable. I will be updating this page with a hardware list, additional parts, and assembly files as I create them. I'm eager to witness the first build!
