An open-source hardware project providing a stronger aluminum extrusion frame upgrade for Prusa i3 MK2/MK3 3D printers, including printed part files, bill of materials, and assembly guides. It improves stiffness, print speed, and precision while reusing most stock printer parts.
Use cases
- upgrade my Prusa i3 MK3 to a stiffer frame
- make my Prusa MK2 print faster and more accurately
- find printed parts and BOM for a Bear frame upgrade
- convert my Prusa i3 to aluminum extrusion frame
- reduce noise and improve precision on my Prusa printer
- build a BearExxa or Bondtech extruder setup on a Bear frame
When to choose
- you own a Prusa i3 MK2(S), MK2.5, or MK3(S/S+) and want a sturdier frame
- you want an open-source, well-documented hardware upgrade with active community support
- you plan to customize your printer with alternative extruders like BearExxa or Bondtech
When to avoid
- you don't own a compatible Prusa i3 printer
- you want a plug-and-play upgrade without sourcing extrusions and hardware
- you need a software or firmware project rather than a hardware design
