CR-10 V2/V3 Hemera (REVO) upgrade

Combined and designed this setup from the best ideas and designs I could find (in my humble opinion of course)

Features:

• Single piece backplate.
• No loss in build volume.
• Nozzle in original position.
• Cable routing thru backplate for nice cable management.
• BLtouch as close as possible to the nozzle and in the same line (offset: X:-36 Y:0).
• Good part cooling with plenty of room for (REVO)nozzle changing.
• Filament runout and runout sensor integrated

Used hardware:

• 9x M3x8 hex bolt (backplate)
• 2x M3x10 hex bolt (fan mount)
• 2x M4x25 hex bolt (fan duct*)
• 5x M3 nut
• 2x M4 nut

*The lower M4 fan bolt needs to be trimmed to ±23mm

Printed all parts in PLA, this seems to hold up fine so far.
Lever and fan duct are printed with 0,10mm layer hight to get a smoother surface.
fan mount and backplate at 0,20mm
no supports required for any parts.

For the firmware I love Nic Wilson work on Nic's Creality 3D Printer Firmware & 3D Printing Support.
This firmware worked well for me with stock V3, V3 with BLTouch and V3 REVO Hemera.
