This is my take on an E3D V6 nozzle case. I took a look at a bunch of other models of nozzle cases on Printables and none of them really fit my bill:

  • Tight Fitment
  • No support
  • Easy to print
  • Full coverage on the sides and not too much leakage
  • Easy to slide in and out 
  • Doesn't need to screw in 
    • Nozzles should be able to slide in and out without worrying about threads which can be difficult to print

I designed this case with these requirements in mind, starting with dealing with fitment. I found that some of the sliding rails in other models can be fairly difficult to print as they are direct overhangs, despite being small. Instead, I did a 60 degree outwards slope followed by an inverse 60 degree inwards slope to make a very easily printable sliding rail.

I also combatted the slop in most other “remixed” case models by designing the case to be direct fit with a 0.2mm tolerance between the cover and the main body. This was fairly robust and tight from my testing, so I added a finger slide strip on the bottom of the cover to easily slide out the body with a push.

Also, was not a fan of the open design so I made the back entirely enclosed.

This was designed to fit nine (9) E3D V6 nozzles with a 5mm nozzle head size (perfect for SliceEngineering Vanadium nozzles, that I use exclusively), but I can easily release additional models with higher headroom. I found these SliceEngineering Vanadium to be just the right size for these, with about a 0.2mm headroom on top.

Print Settings from my tests

  • Raise3D E2
  • Unreleased PLA+ Black [own brand]
  • 0.6mm nozzle size
  • 0.66mm extrusion width
  • 0.25mm layer height
  • Special Concerns
    • I recommend dialing in your z-offset for your first layer on the main body very well. Because this is a sliding fit, any elephant's foot will cause major fitment problems. Alternatively, turn on elephant's foot compensation to -0.2mm on contours P

Print Orientation

  • Print the main body with the rails pointing upwards and the large flat surface touching the build plate. The holes should be open from the top
  • Print the cover with the opening towards the sky

Specifications

  • Nozzle Support: E3D V6 (M6 threads), 9 total
    • Note: Hole size was enlarged to 6.2mm to account for even shrinking filaments
  • Headroom (from shoulder to tip): 5mm
  • Threading: None
