Full Bear MK3 X/Z Lineal Rails MGN12

thingiverse

I have designed a Prusa Bear MK3 with complete MGN12 rails. There are similar ones for other printers, but not for the Prusa Bear MK3. After much calculation and testing, I present my finished work project. I have also developed it for Bear X-Carriage and Bondtech Bear X-Carriage. I tested it with Bondtech and it should work the same for the Bear X-Carriage. You just need to move the position of the frame's Z axis. If you used a 106mm build helper when assembling the frame, it changes to 93mm so the position of the extruder is the same. Update 03.01.2020: I have added Version 2, which eliminates the need to align the rail and is connected to the Z_Motor_Mounts. You can continue to use the old variant. Furthermore, I added X_End_Motor_and_Bearing and Cover, but didn't test it, but it should work. The printer has passed the self-test and XYZ calibration of the original FW.
