Diesel Heater 3 inch Intake Flexible Vent *3D Printable
Couldn't load pickup availability
This flower-shaped vent is designed to stay on your cold-air intake, not the exhaust side. Works with any heater with a 3 inch outlet. It’s printed in flexible TPU, so you can step on it and it won’t crack like traditional plastic. Add a bit of heat and it will even reform.
It’s a cute little upgrade for your heater setup. Unlike sealed caps that get lost easily, this vent is meant to stay on full-time—and its vibrant color makes it both functional and fun.

We’ve implemented two key design changes to the Combusto heater for improved safety, usability, and long-term reliability.
1. Intake Ducting Removed
The clamps and brown ducting that used to bridge the intake outlet (right side) have been removed by default. We’ve added a new fan cover and a 3D-printed vent cap for the outlet.
With a 5kW heater, circular airflow isn’t necessary—pulling in cooled air delivers better performance.
2. Power / LCD Panel Port Relocation
We’ve relocated the power port and LCD panel connectors to the intake side of the unit. This follows our new design philosophy that Hot components remain on the exhaust side and Cool components are positioned on the intake side. The result is better thermal separation, safer handling, and a cleaner internal layout.
