P3Steel MK2

The base for this remake is 3mm lasercut 2.5DXL version.

####Changes to original design:

+ changed Z-TOP hole to 22m for Z axis bearing
+ redesigned Z-TOP so no MK2 extruder should hit the frame (not tested)
+ added 4mm holes in bed for SMAs
+ added holes in frame for power supply and rambo housing (M3 thread)
+ enlarged frame so now it's possible to use MK42 from Prusa I3 MK2/S
+ added and repositioned holes for cariage for MK42
+ added adtitional holes in frame to secure 8mm smooth rods
+ redesigned Y idler to follow belt geometry (not tested)

####For printed parts:

+ mirrored RAMBO housing from Prusa I3 MK2
+ created Y-Endstop
+ remixed Y-belt holder for use with SMA's
+ remixed X-ends to match endstops and smooth rods

####Please note this is early working prototype stage, might not be suitable for production use. Few things need to be still designed.
