Hydrometer Holder

This is a wall mount bracket for a battery hydrometer.

My motivation to design this is because I needed a way to safely store my hydrometer without deforming the pickup tube, and also to allow a way to catch the acid drips.

You can screw it onto a surface, os use double-sided tape.

I add a pinch of backing soda into the bottom cone to neutralize the acid drips.
