Description
This 3D print template offers a practical and efficient solution to improve air circulation in motorhomes and caravans with a Heki Mini roof window (40x40cm). The fan insert is precisely integrated into the roof window, ensuring a continuous supply of fresh air and better air exchange inside.
Ideal for warm days, the fan reduces heat buildup and provides a pleasant indoor climate – without extensive modifications. The design is compact, lightweight, and specifically tailored to the dimensions of the Heki Mini.
The fan can be powered via a direct USB connection in the vehicle or via a power bank.
The following components are required to build the model:
1x Fan set (140mm)
1x PWM controller
8x M3x5mm heat-set inserts
The accessories supplied with the fans are used for fastening and wiring
Features:
- Perfect fit for Heki Mini roof windows
- Improved air circulation in the vehicle
- Easy assembly without soldering
- Easy installation without drilling or gluing
Lightweight and stable design
Assembly:
The fan is simply inserted into the open roof window and can be removed at any time if needed. Optionally, a small fan can be integrated (depending on the version/design).
Construction:
- Print all components and, if necessary, rework the areas where the supports were.
- Slide the three parts of the base plate together
- Insert nuts
- Wire the fan and PWM controller using the fan cables
- Pull off the PWM controller knob
- Screw the fan into the outer corners using the supplied screws
- Insert the PWM controller into the corresponding recess
- Attach the cover plate, either with or without the power bank holder, using the 4 remaining screws.
- Lightly sand the PWM controller knob and then attach it
I was inspired by a model for the Midi Heki roof hatch
