M-Cube, a tiny CoreXY 3D printer

So, this is my 3-rd printer. It's designed to print small objects, up to 160x160x160mm. External dimensions are 315x315x320mm. As usual, it made of aluminum profiles 10x10x1mm, hardened rod 8mm and many bolts&nuts M3. As hotend is used CR10. Motors are some Nema14 for XY and some Nema17 for Z & E. There is Creality silent mainboard v1.1.5 and 3DTouch for autolevel bed.
I was printed all parts from PLA except motor holders, X-carriage, hotend holder and hotend cover, these parts are from PETG.
