Summary

This is a simple tool I made to help me remove the ring from the bottom of a Nautilus atomiser on my e-cigarette. The original Nautilus tank needs the bottom ring separated every time it is refilled, and it can be very hard to twist off. With the newer version 2 I only need to remove the ring to change the coil, but even that can be very difficult and annoying.

Mostly that's because there's no easy way to grip it so this tool is intended to slip over the ring and be pressed so the small piece of plastic sticking out slips into the vent slot. With some pressure on the tool it's then much easier to twist the ring off. I made the tool to just fit over the tank, so it won't break in use. However, if it's pressed too hard when not over the ring it's likely to break unless printed with a flexible filament, so please be careful.

I designed this with OpenSCAD so I've included the design file in case you'd like to modify it.
