Sneaks' work is awesome! The only improvement that stood out to me was a base 20 rail mount. He has many rail models, but the closest he seemed to have for a Prusa Bear was a base 30 model, as that's what prusa uses on the mk3s and Mini, but the screwhole also seemed to be designed for M3 screws. I modified with M5x12mm (and maybe 10mm) screws in mind, and can handle button heads or socket caps.
The author remixed this model.
