Opener for Ceres Chill

The connector of the Ceres Chill can seal very firmly to the bottle after being chilled. This tool rests over the connector, allowing you to twist it more easily.

I have included a slight taper to the tool head. This should help the tool drop into place, and should allow it to work even if your printers tolerances are off by up to .4mm or so. YMMV - post if you have issues.

Printing:

I used the stock print settings for my nozzle, plus ironing to provide a nicer finish. No supports are needed. Stresses are along the layer lines and the geometry is simple, so bumping filament temperature and increasing perimeters will result in a stronger print with no real downsides. I don't think it's necessary, though I haven't tested it to failure :).

I printed in PLA, you may want to use PETG to avoid deformation in case the tool is left in a hot car.
