3D model description

https://www.buymeacoffee.com/squirrelf

Adds rigidity compared to the original mount I made.
Should allow nozzle change without holding the heatblock

( not compatible with mars orbiter, which has it's own derivative of this )

The nozzle will only be 8mm further than the original hotend, and about 0.5mm height difference.

Requires:

  • 4x screws m2.5x8mm (those were included with my dragon hotend)
  • 3x screws m3x8mm for mounting it to the gantry plate of the ender3 (two on the front, one in the back, which requires loosening the gantry wheels to install)
  • 2x screw m3x10 or m3x8 for securing part one and part two together

Install steps:

  • lossen the X carriage top left wheel and bottom wheel (keep top right wheel tight), you should have enough play to derail it, and access to the back of the plate (you can disconnect the belt to make it easier)
  • mount and secure part two to the back plate (use two m3x8 on the front, and one m3x8 on the back )
  • separate the extra top part (v6 type part) of the dragon hotend if you haven't done so yet
  • mount the dragon hotend to part one (make sure your orientation is correct), using the four m2.5x8mm screws (included with the dragon hotend extras)
  • slide part one (with the dragon) up under part two, and secure it with two m3x8mm or m3x10mm

This mount will work with the solar orbiter duct

3D printing settings

  • No support needed
  • I printed it at 0.1mm layer height, but any reasonable layer height should do
  • 10% to 15% gyroid infill
