Bůža MK3B Upgrade for MK3S+

Prusa MK3S+ to Bůža Research MK3B Upgrade. Voted the most cool upgrade in the universe.

• Modified Einsy/Rambo case to acomodate larger screws for attaching the extruder and heatbed cable bundles. No more cracking. Cooler appearance. Significant increase of swag.
• BůžaLink cover to cover up the RPi Zero W and the micro USB cable for an ethernet dongle as seen in one of the photos. An external PCB antenna for the RPi zero W fits in too. Compatible with all versions of Einsy-base after you cut out the opening for the RPi. Attaches with M2 screws. (MK3S IR-Sensor/MK2 endstop ones, M2x8)
• Rambo hinges are rotated for better part strength, no more cracking.
• Super-cool Bůža Research LCD cover with easily accessible SD card slot.
   Please use the bundled 3MF file so the first layer has all the details.
• Modified Bear x-ends, reverse compatible with physical X-endstop.  X-motor can go both onto the front or back. If mounted to the front of the X-axis, pinout must be reversed in the motor connector. X-end-idler accomodates a small screw head for the ider in it. There is an opening for easier removal of the idler mount by inserting a screwdriver from the side. Easier X-belt tensioning. Please do not use any screws to fix the Z-axis bearings in place. Yes, there are points to attach screws and nuts to, but just don't do it, you'll ruin the bearings.
• Better X-carriage, no more scratched X-rods!! Bearings are now collinear, no longer resemble a V-shape, no longer getting seized. Accomodates a possible longer screw for the fs-lever.
• Better X-carriage-back. It is special and there is Bůža Research logo on it.
• Extruder body modified so the adapter-printer clicks in better.
• Extruder removal made easy without having to disassemble the extruder.
