Matrix (Hemera) Clipable Shroud

Part cooling fan shroud for the Trianglelab Matrix extruder.
Maybe compatible with the E3D Hemera/Hermes extruder as well.

- Low impact on horizontal section: 10mm thick.
- Easy to clip on and off: only small attaches remain on the extruder when off.

Necessary parts:
- 1 x 5020 Cooling fan.
- 4 x M3x5 flat headed screws for the attaches.
- Some duct-tape that has some good sticky-like surface for the friction fit of the fan.

Printing:

- Use ABS or other temperature resistant plastic.
- Have your "Horizontal Expansion" (Cura name) setting calibrated so that a X mm cylinder will fit into a X mm hole. This setting could have an other name in slicers other than Cura. A typical value for FDM printers is around -0.1mm. A more negative value will give a larger clearance.
This point is important as there is very small clearance in the object dimensions.
So, either try with -0.1mm or calibrate your Horizontal Expansion setting with the following: https://www.thingiver
