mk4 BOM

Notes:
-- I am in no way affiliated with Prusa Research a.s. and
   i have not made any original work this is just a compiled list of components made from their freely avilable assem manual for the mk4
   linked here: https://help.prusa3d.com/category/original-prusa-mk4-kit-assembly_1967
-- this is a rough BOM i extracted from the assembly manual of the mk4
-- i have noted that motors accessory are not included like the z axis screws and every cable for the steppers
-- 3d printed parts are available from their printables.com here https://www.printables.com/model/451501-mk4mk39-printable-parts/files
-- extrusion have 4 tapped M5 holes 20mm deep on the corners as stated here https://github.com/prusa3d/Original-Prusa-i3/blob/MK3S/Frame/Extrusions.pdf
