Vent covers for Zen Float Tent (v2)

Update: 2019-05-24

I've added a variant for the newer zen inflatable tank, which has thicker walls/vents. I designed this one based on measurements I received, but I haven't tested it myself. If someone prints a set and tries them, I'd love to know if the length is right.

This is an improved vent cover for the vents on a zen float tent.

The inner fins on the zen's vent cover have a tendancy to break off, and are a bit annoying to insert into the vent.

This version has heftier fins that are tapered at the end, for ease of insertion, as well as a central post that allows the inner cover to be inserted into the outer cover.

The central post has a keyway that provides a closed and open position. In the closed position, the inner cover is pressed against the vent, to help avoid the humid air escaping.

And of course you want a little bit of airflow while floating, to replenish the consumed oxygen in the tent. You can easily twist and pull the inner cover to move it to the open position, where there is a 10mm air gap to allow air movement.

When installing these, first insert the one with fins on the outside of the tank, and then insert the other one on the inside. I recommend taking a look at the keyway and playing with the keyway mechanism before putting them on, so you're familiar with how they move between the open/close position, and how to remove it.

The one downside I've found so far is that it's difficult to remove the vent covers from the outside. You have to get in the tent and remove it from the inside first.
