A complete set of 3D models for building a DIY ventilation chimney. The design connects four PVC pipes and creates a functional, weather-protected ventilation system, ideal for outdoor use.
Included parts:
- Connector (T-joint) – designed to join two PVC pipes Ø110 mm and two modified PVC pipes Ø95 mm.
- Two spacers/adapters – provide the correct distance and stability between the pipes.
- Protective cap/hood – prevents rain and snow from entering.
- Insect & small animal protection grilles – mounted at the outlets. Each grille consists of two parts, allowing you to insert a fine mesh (e.g., mosquito net).
- Bottom grille (inside the T-joint) – for extra protection against dirt and pests.
Assembly:
- Four pipes (two Ø110 mm and two Ø95 mm) secured with screws.
- The gaps between pipes should be filled with expanding foam – this makes the chimney insulated and sealed.
- Best material: PET-G, resistant to moisture and UV exposure.
Print settings (suggested):
- Material: PET-G.
- Layer height: 0.2 mm.
- Infill: 20–30%.
- Supports: required for hood and grilles.
- Orientation: according to natural mounting position.
Notes:
- Can be scaled in slicer to fit different pipe diameters.
- Extra sealing recommended (e.g., glue or silicone).
- Designed for outdoor technical use.
