Sprite Nova V2 - Customisable Sprite Extruder Shroud and Dual Fan Duct Ender 3 S1 Series

I previously released the Sprite Nova cooling duct for Ender Sprite Extruders here.

This new version is has been redesigned for easier printing and customisation:

• New front plate design which can swopped out
  • Source STEP file has been included so you can create your own designs
• Front plate can either be connected with 6x3mm neodynium magnets or the included Connect Peg model
  • More designs will be released soon
• Improved bottom slotted design that significantly improves nozzle visibility

Summary

• Requires only 8 6x3mm neodynium magnets, else print 4 of the peg models
• Requires no modifications of the Sprite Extruder
• Uses the standard Creality 4010 blower fan
• Uses 3 screws that held the original fan mount on

Print Guide

• Print the shroud face down using tree supports to assist the internal bridges
  • This is to ensure the surface is as flat as possible to avoid gaps with the front plate
• Print the front plate with the back side down 
  • This is to ensure the surface is as flat as possible to avoid gaps with the shroud
  • You'll need to add supports - recommend using grid
• Print the jets vertically with the jet nozzle on the bed side
  • No supports required

Sprite Disassembly

1. Disconnect and remove the Sprite Extruder from the printer
2. Remove the touch probe
3. Remove the fan duct and keep the 3 M3 screws
4. Remove the 4010 fan using

Front Plate and shroud assembly

• Magnets
  • Stack all the magnets vertically together
  • Using a permanent marker, mark one side of each magnet so you know it's polarity
  • Insert the magnets into the shroud, and as the fit is very snug and you won't get them out again without damaging the print, be careful to insert each magent with it's correct polarity
  • Insert the magnets into front plate, ensure the polarity is correct!
  • The front plate should adhere very well to the shroud, but test that no magnets are loose and come out when you pull off the front plate
    • If magnets do come out, use some CA glue to lock them place (triple check polarity!)
• Pegs
  • The fit should be snug
  • Follow same process as magnets
  • Use CA glue only on the plate side, not the shroud

Final Assembly

1. Carefully insert the 4010 fan into the shroud from the front side
   1. You will need to tilt and wiggly it in carefully - it is a snug fit and no screws needed
2. Insert the fan duct into the shroud
3. Place the unit over the stepper motor and take care to position the probe and fan wires so the don't get pinched
4. Do final alignment with the screw holes on the stepper motor, and screw in the 3 M3 screws.
5. Re-attach Sprite Nova extruder to the printer and ensure
6. Ensure the toolhead is square to the bracket
7. Snap on your front plate
8. Redo your z-offset as this has probably changed slightly
