Conical Snap-In Cap Ø70 mm
Print Profile(1)

Description
Snap-in cap designed to hermetically seal 70 mm suction pipes, ideal for 3D printer fume extraction systems or domestic ventilation/extraction systems.
The cap features:
- Conical profile for easy and guided insertion
- Pressure fit without screws or clamps
- Completely closed top part, to prevent the escape of fumes and odors when the system is not in use
- Top gripping edge, which makes extraction easy even after long periods of use
The design aims to ensure a good compromise between seal, ease of assembly, and durability over time.

A cap with a maximum diameter of 70 mm, designed with a conical profile to facilitate insertion into the pipe and equipped with a top edge that makes manual extraction easy. I personally use it to close the exhaust pipe of my A1 Mini printer when it is not in use, to prevent the escape of any residual fumes or odors. For applications on hot air intakes or fume extraction systems, printing in PETG is recommended, as it offers better heat resistance and slight elasticity useful for the pressure fit.
