3D Printed elements of air conditioning/ventilation systems.

Okay, the longer one is E9, the shorter one is E24/E21. What about the third one in the photo?
It's in 2800 from the USA.
It's different from the others.

Regarding bases? Which one is E9 again?

The one with the extra window is for the E9, the shorter one for the E24/E21.
The third one in the photo below is installed in a Nevada 2800 imported from the USA.
The front is completely different.

It is exact match to that in my '75 Euro CS.

It appears that the E9 model had two different evaporator bases.
Perhaps these differences exist in the construction of the evaporator base in pre- and post-facelift models.
In any case, the original A/C evaporator base is difficult to replicate.
Every craftsman I spoke with about this said it was certainly possible, but it wouldn't be cheap due to the shape, which requires more precision and time to replicate.
I think the best solution would be to redesign the base to standardize and simplify its construction while maintaining its functionality.
I see what you mean. Could the first one be e3 as the console is very different?

I think the longer ones with a window are only for E9.

I'll keep you updated on progress.
 
looking forward to hearing of your development on this ... of course then there is the decision of where / how to put in other vents. one approach is to connect them to the defroster vents. another is to do something in the panel under the steering column ... the passenger side is a little more difficult - perhaps under the glove box. i am curious how a flexible duct will work around the passenger glovebox supports

Why not route the air up to and out of the speaker grille? I personally like fresh air blowing at me when driving
 
Hello after a long absence.

We're slowly approaching the end.
In about a month, a complete air conditioning system will be available, modeled after the factory one but equipped with modern components.
We're currently conducting final tests and minor modifications.
The kit will allow for air conditioning installation in any E9 that wasn't factory-equipped.
Plug and play installation.
No modifications to the vehicle's structure are required.
The system is adapted to the new refrigerant.

The kit will include:

- Sanden compressor with bracket for the M30 block.
- Compressor drive belt.
- Condenser with fan.
- Drier.
- Refrigerant service connections.
- A complete set of system hose connections.
- Refrigerator hose to be cut to the correct length.

- Evaporator with a modern core and fan.
The exterior of the evaporator housing will be identical to the original.

- Evaporator air duct.
- Evaporator base.
- Side panels with inlet openings and inlet covers with an elephant skin texture, just like the original.
- Central panel with markings in English or German, along with modern climate control parameters.
- Radiator fan thermoswitch
- Relay.

The photos below obviously do not show all the components.
We are currently in the final stages of improving the efficiency of the cold air vents, and everything indicates that the next upgrade will be a modification to the cold airflow, which will allow cold air to exit through the windshield defrosters. This will prevent cold air from escaping exclusively through the heater outlet vents.
This should improve cold air circulation in the cabin and cool it more quickly.
All printed elements are currently available. The entire set will be available from mid-March. If interested, please send me a DM.
Questions and comments are welcome.


It's winter, and a friend's workshop is preparing for the season.
I couldn't resist passing by.
The last two photos.
A work of art on two wheels...
