Cooling system to replace stock CS of Creality K1. No major geometry changes, just optimized for FDM printing.

==========

Система охлаждения для Creality K1. Никаких значимых изменений в геометрии, просто оптимизирована под FDM 3D печать.

Inspired by Orca Slicer VFA test, but reworked to be used in other slicers. Also changed angles of beams and added thicker lines to separate segments from each other.

**For PS/SS:** just use .3mf file. Most of print settings already made.
**For Cura:** use .stl model and change perimeter speed with post-processing.

# Why this print head?

+ Fits any 3D printer, that uses ender-3 ot similar X carriage
+ Printhead can be removed for service by unscrewing only 4 screws
+ No print volume losses on most printers
+ Easy to print - no supports needed
+ Improved air flow for both hotend and model cooling

### BOM

+ BMG or clone (right)
+ E3D V6/Volcano/Dragon/Dragonfly/NF-Zone hotend
+ 40x40x10 axis fan for hotend
+ 1x or 2x 5015 turbo fans for model cooling
+ 3x M3x6 round head screw
+ 2x M3x8 round head screw
+ 2x M3x10 round head screw
+ 4x M3x12 round head screw
+ 2x M3x16 round head screw
+ 4x M3x20 any head screw
+ 10x M3 nut or M3x4 heat-set insert

### Print settings

+ Models are made for right BMG
+ For base and mount use any filament with ~80°C heat resistance (PETG, ABS, ASA, HIPS, PA, PP, PC, etc.)
+ For fan ducts use any filament with ~100°C heat resistance (ABS, ASA, PA, PP, PC, etc.)
+ Models are already placed in correct printing orientation
+ Models are created for 0.4mm line width and any layer height. If you plan to use other values, check layer preview to find wrong pathes.
+ Use 3+ perimeters and 100% infill for max rigidity of mount

### Updates

28.12.21 - Increased strength and rigidity of parts
12.01.22 - Increased strength and rigidity of base part
13.06.22 - Increased strength and rigidity of all parts
17.10.22 - Icreased efficiency of fan duct + added BLTouch mounts
25.10.22 - Added mounts for Voxelab Aquila

## Summary

Cooling system and mount for Creality Sprite extruder.

- Cooling system fits any Creality Sprite extruder or Creality Ender-3 S1/S1 Pro/S1 Plus;
- Cooling system is very powerful and can cool any filament even on volcano hotend's maximum flow;
- Cooling system can be used with V6/CR-10/Volcano hotends;
- Mount for Ender-3 style printers have 2 variants: for stock Sprite's 3010 fan or for stock Ender-3 4010 fan;
- All parts can be printed without supports;
- It's open source. You can download .stp file and change everything you need.

## Instructions for Ender-3 S1/S1 Pro/S1 Plus

You will need for assembly:

- 2x 5015 24v fans;
- 2x M4x20 DIN 7380 screws;
- 1x M4x35 DIN 7380 screw.

Cooling system can be printed without supports if you will lay it on front side.

## Instructions for Ender-3

### What to buy

- Creality Sprite extruder. Prefer plastic version without fans;
- Bi-metal heatbreak for sprite extruder;
- V6/CR-10/Volcano heatblock, nozzle, sock and thermistor;
- 2x 5015 24v fans;
- 3-4x M3x8 DIN 7380 screws;
- 4x M4x20 DIN 7380 screws.

For BLTouch/CRTouch (optional):

- 1x BLTouch/CRTouch sensor;
- 4x M3x5 DIN 7380 screws.

### How to assemble

There is [very detailed instructions](https://k3d.tech/esp/) on how to print and assemble this project in russian language. You can use any translation app to read it.


K3D Sprite cooling system

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:6089483.

For assembly you will need:

- 6x d10x1 magnets
- 4x M3x8 screws
- Any universal glue

Grille parts prints without cover and bottom layers, only infill. I user 30% honeycomb, but you can use any other.
