Scuba BCD floating vent puller

I designed this puller for my sidemount wing, as sometimes I find difficult to locate it when wearing a drysuit, so now they float slightly and they're easy to locate

I recommend printing it at 100% infill to avoid squeeze issues at depth, and use some sort of foam to add buoyancy even if the superglue doesn't seal the sphere completely.

The design will fit the OEM cord of an Xdeep Stealth 2.0, although if you have troubles feeding it through, you can work the hole a bit with a drill bit or something. All the walls are 2mm thick.
Alternatively you can resize it to a bigger scale, but I wanted to keep it as closer to the original size as possible.
