Rooftop Tent Pole End Cap & Rain Guard / O-Ring (5mm, Thule Tepui Kukenam 3)

These are two simple but useful 3D-printed parts for tent poles with a 5mm diameter, originally made for the Thule Tepui Kukenam 3 rooftop tent (but should fit similar tents too).

One is an o-ring that helps stop rainwater from running down the pole into the tent. The other is a small end cap to protect the tent fabric from getting damaged by the pole tip.

The end cap is a press fit and stays in place. The o-ring is loose enough to move by hand but won’t slide on its own.

I printed these in PETG, but I recommend TPU for the o-ring (flexible) and ASA for the end cap (UV-resistant).

These are small parts but very handy, especially if you’ve lost the originals, as they are very loose (after 2 years of not very much use)

Included Fusion 360 file if you want to tweak it to fit.
