This is a replacement cap for your Permatex aluminum anti-seize lubricant. The bottle comes with a brush attached to the metal cap, but the brush always breaks off before the bottle is empty. This cap will hold the brush (or any acid brush with a .25" metal handle).
The brush handle can be inserted into the cone, and held in place with a #6 x 1/2" sheet metal screw. I thought about making some sort of printed clamp but sometimes simpler is better.
