MK3 MK3S MK3S+ to MK4S - Cheap Upgrade with only printable parts (STL's)

Installation and Build

Assembly parts per the instructions here: https://help.prusa3d.com/category/original-prusa-mk4-kit-assembly_1967

Notes for build:

• X-Axis belt will need adjusting, as the stock MK3S+ (Non-MK4) belts and extruder body are a tad short compared to the length needed (But you can make it work).
• Without any other updates, I ran the full calibration cycle and the whole printer passed without a fail.
• You will need a pin for the Idle body (Step 35 in the manual, guiding the X-axis). Otherwise you should be able to locate most needed hardware via a small parts box from Amazon or a trusted source.
