Ultimate 5015 Part Cooling Dual Fan Duct for Ender 3 S1 (Pro) + Sprite Extruder

CHECK OUT MY NEW RELEASE → 5015 Hot End Fan Upgrade for Ender 3 S1 (Pro) + Sprite Extruder

Design:

I have created this model with the following considerations:

1. dual, symmetrical airflow under the nozzle
2. to be as light as possible- weighs @ 20 grams only
3. snap-on mount 1x 5015 blower (24V)
4. retain maximum printing visibility 
5. to have shortest & as straight airflow as possible
6. clear CR Touch probe
7. avoid magnetism of the extruder motor
8. not to suck in strings from print

Printing instructions:

• printing orientation on bed as shown in pictures
• material: use PETG or better (avoid PLA, due to low heat resistance)
• layer height: 0.2mm or smaller
• enable supports → recommended to use PrusaSlicer 2.6 Alpha 3 or similar slicer to use Organic / Tree supports LINK https://github.com/prusa3d/PrusaSlicer/releases
• use at least 4 perimeters
• infill: any
• note: most of the model has 40°+ Deg overhangs

Fitting instructions:

• after clearing supports, use 2x M3 bolts (ideally 8mm length, or use nuts to shorten any longer bolts you may have)
• use 24 Volt 5015 blower and splice/solder/crimp onto a stock connector
