Smart Roadster - Mise à niveau du ventilateur intercooler surdimensionné

Oversized fan frame for the intercooler of Smart Roadster (452) and Smart Fortwo (450).

This frame allows the use of a larger 200mm fan. The better blades design and larger dimensions allow better air flow, compared to the original one.
I used this one and works just fine: https://shorturl.at/NWtnv
Alternatively you can buy this one, which is a REAL SPAL and not a replica: https://shorturl.at/ANKGA
To complete che work you will need:
- the fan linked above or similar
- the connector you prefer (pay attention to the direction of rotation of the fan, it PULLS air and does not PUSH)
- 4x M6 nuts (better if self-locking)
- 4x m6 bolts.

Printing advice: I printed some for tests in simple PLA and it seems to be fine as a material, however I STRONGLY RECOMMEND, to avoid bending, using a filament that resists high temperatures such as PLA HT, PETG HT or similar, it must withstand around 100°.

ATTENTION: the throttle body hits the fan, so you must rotate it with the black plastic part facing up, like in the pictures. It won't touch the hood if you have the engine mounts in good condition.

Bonus: If you have other fans and want a different hole pattern to mount them, feel free to contact me and I'll see if I can provide you with a file with the specs for your fan.

____IMPORTANT UPDATE____
Following feedback from some users asking for different fan sizes, I’ve updated the design by adding two more options.

One allows the use of a smaller fan and does not require rotating the throttle body (which causes problems for some users, as it hits the panel that closes off the engine bay).

The other is completely closed and universal, and can be cut to fit whatever fan (or fans, in the case of multiple smaller fans as some users do) you want to use.

Thank you for the feedback, and above all, thank you to everyone who inspires me to keep improving

• High temp filaments HIGLY RECOMMEND
• Infill 100%
• Print it with the flat face on the bed
• The bed size must be at least 230x230

Some people have experienced minor issues with the throttle body rotated by 90°, which can make contact with the “bonnet” area. One of them found a good solution to this problem: a 3D-printed “bump” to be placed on the bonnet to create clearance for the throttle body and prevent it from touching.

Of course, the new piece must be cut and glued in place, but it causes absolutely no issues once the original carpet is reinstalled on top of it.

--- I'd like to sincerely thank my friend Michel for coming up with the idea and providing the file. ---
