Ender 3 triple 40mm direct drive conversion with v6 hotend (REMAKYR v3.1)

It's a third version, so most of errors and breaking stuff was fixed. First version had geared extruder, maybe in V4 i will bring back that feature. For now reliability comes first.
It took me a long time to create the whole thing (about 2-3 months, testing and rest of stuff). So consider supporting this project or me if i helped you ;d

About current mod:
Mod uses stock extruder, extruder motor and base palate from ender 3.

You get full build volume, 0 collision and great weight distribution on base plate.

Extruder is mounted 180 degree (for weight distribution and frame collision). Because of that you will need 8-9mm M4 screw for extruder runner, longer screw will collide with nema mount. You can unscrew one from ender 3 frame i get mine in that way.

You should get something around 51g of used material, without brim is 50g. If you want full infill it's about 60g, so not that much more. With ABS it should be lighter than that.

For screws info and build plate placement look at the photos

Material used to print that thing was a premium PET-G - Devil Design blue translucent 

Assembly - In order with first file number

To reduce clearance of fan duct, print spacers or use metal ones. For me 2x 0.5mm spacers work fine.

PRINTING PARAMETERS

• Quality
  • layer height: 0.08-0.16 (for bonding - lower is better)
  •  nozzle: 0.4mm
  •  
• Walls 0.8mm is good enough
  • Horizontal expansion 0, but you might need 0.1mm (for hotend base).
  • Wall ordering: From outside to inside
  • Minimal line width: 0.2mm
  • print thins walls: yes
  • minimal feature size: yes
• TOP/BOT 0.8mm
  • Pattern: Zigzag
  • Skin overlap percentage: 20%
  • Monotonic Top/Bottom order
  • Ironing - YES
• Speed
  • Infill 48 -Outer 15 -Inner 24 -TOP/BOT 24 -Travel 150
  • Initial 15 and initial travel 100
• Infill 
  • pattern: cubic
  • density: 20%
  • infill line multiplier: 2
  • connect infill lanes: YES
• Material
  • ABS or PET-G (ABS is better and lighter than PET_G)
  • Printing temp: 250C with PET-G. You can try 230C if your cooling can't keep up, but it will be weaker.
  • build plate: 75-80C
  • Flow 101%
    • Outer wall flow: 100%
• You don't need supports, but you need really good cooling
• Travel: retraction: 1mm (direct drive)
• brim: 3mm
  • distance 0.025mm
• Cooling yes 100% for dimension accuracy and overhangs
