90 Degree Airstone Adapter

I made this to get a topfin airstone to fit properly into my etchant tank. Don't use this for real fish unless you know that your filament/resin is safe for them.

Fitting is a 5mmOD so scale appropriately.

This probably shouldn't be used under any sort of pressure. No modelling or testing has been performed to this end.

I'll update this once I have printed it and can add some images of it in use.
