Retevis RT95 Cooling - 120 mm Fan Mount

📄 Description

Does your Retevis RT95 get quite warm while transmitting?

Then this mount is the perfect solution: It provides active cooling directly from above – with a quiet, standard 120-mm PC fan.

Installation is straightforward: Two mounting arms attach to the original RT95 mount. An integrated honeycomb grid protects against contact and prevents objects from entering the fan.

An opening for a 25 mm round switch (12 V) is also provided, allowing convenient on/off control of the fan.

📌 Note

Specifically designed for the Retevis RT95.
May also be compatible with similar devices – please check dimensions.

This is my first MakerWorld project and my first model in FreeCAD!

Therefore, apologies if the model is not perfect, I am still learning.
