Welcome here and thank you for reaching this place 😊 . I am Greg and I love well thought designs! You may have heard about me for the Bear Upgrade frame and extruders compatible with Prusa 3D printers.

The main goal of my Bear frame and extruder projects is to increase reliability because it is annoying to have to repair a tool in the middle of a project. They also improve quality, speed and makes maintenance and assembly smoother. My Bears are truly open source with original CAD files, mechanical drawings, boms, ... so that you don't have to redesign everything to make a simple improvement. Sharing the knowledge is very powerful and matters!

I do a lot of testing and research and therefore I have to regularly buy measuring tools, genuine products, software, filaments and other special hardware. Be sure that every sponsoring will be taken with precious care and deeply injected in the project.

Thank you ❤️
