From the original design, I just added two screw holders for the print fan to mount on top (not pretty but it works). I removed the FS cover (from the original design) to quickly mount and dismount it. So when I need to print strong ABS parts in a heated enclosure (I don't need the part cooling fan on those cases), I just unscrew the print fan, add this fan holder and screw the print fan on it.
INSTRUCTIONS:
- Print it with default profiles, no supports on ASA/ABS/PC.
- Remove the textil sleeve, and extend the layer fan cable about 4 cm.
- Add two square nuts (from the spare bag)
- I recommend to add some silicone to the nuts and to the cable holder.
- Activate “KEEP FAN ALWAYS ON” and set fan speed you want.
- To reduce the E motor temperature even more, I recommend to add the following code at the START G-CODE (it will reduce the E motor current): M907 E410

UPDATE:
- I improved the attachment to the engine.
