Original Prusa Mini+ Bear mod

today, I finished the main modification of the printer (I only want to change the wires soon) so the whole frame is changed, the hot-end, extruder, heatbreak and nozzle, and all printed parts were PETG are now ASA, instead of a Cantilever design it is now an H-frame with double Z axles, so the frame gives rigidity and structure to the printing, yet still running the original Prusa firmware (with some added G-codes)
