This modification was initially adopted to achieve better results with flexible filaments (using a direct drive extruder) and a stiffer frame for faster printing. Since then, Input Shaper was given as a free upgrade to the Prusa MINI making this project sort of obsolete (for my goals at least). As such, this project is discontinued. I am leaving it here if for any reason anyone might want to experiment with the design in the future.

Credits:
A big thank you to the developers of the Prusa Bear (and Bear MINI) and subsequent remixes that I used for this mod, namely gregsaun, pear3d.ch and Tomson, and of course Prusa Research.
Disclaimer: The Original Prusa Mini+ is an amazing little printer and as far as I am concerned the print quality is incredible for the price and ease of use. I chose to proceed with this build because as many others, I enjoy tinkering with 3D printers towards the possibility of improvement. In this case, towards a possibly more robust frame, which would (in theory at least) allow to maintain the same quality at higher accelerations with a direct-drive extruder to ease printing of flexible filaments. Keep in mind, as with any DYI assembly, there is always a chance of the final produced print quality to suffer, as it depends on the sourced hardware quality, part design and on the actual skills and experience put into building.
Background:
There are quite a few models and tutorials online (mainly in Printables) to build your Prusa Mini Bear mod, but as soon as you try to dive into versions and part compatibility, it becomes chaotic. Before printing, I wanted to ensure that all parts are well aligned and compatible with each other, but as far as I could find, there was no published CAD version with a complete model. Either I had to make a collection and hope for the best, or work on my own remix.
Main issues:
To fix these, I did the necessary modifications to the Fusion 360 designs I could find (see credits), as well design several parts from scratch.
If there is enough interest I will accommodate a guide for this version.
Cheers!
