Remixed hotend cap for Ender 3
You MUST to print this thing with ABS or filamanent similar by temperature resistance. This shell will closely contact to hotend and even ABS will be slightly melted.
What for this thing
The stock metal cap provides parasitic wind, which blows to the model. As the result, printing with ABS without thermobox impossible. But, with that cap you can do it!
As a proof, just take a look to photos. This version was printed with the cap from the original thing. And there no broken layers.
What the funny: you need to print this shell with ABS in time when you have only the stock metal cover with the huge holes.. Good luck :)
What is remixed
- remove back thin stick at the bottom. It only prevents to set the cap.
- for the front fan - through out holes 3mm
- on top - a single window for cables and radiator. There is no need to guide and split into sections.
- the size of the box is increased, the front fan is further from the hotend at 4mm.
20%, walls - 1.2mm (3 layers)
If you using Cura, set up "Enable Support Roof". It should give you a better view of fasteners.
After installation make sure that cap fits snugly to the plate of the hotend (see photo #3). Due to I removed the back thin stick at the bottom, the cap may bend away from the plate.
