Spoon Holder for Spa Chemicals with Customizer

I prefer to keep appropriate-sized measuring spoons with each of my hot tub chemicals.
This is designed to fit around the neck of a small chemical tub and hold a long spoon
It's sized for Arctic Spa ArcticPure brand hot tub chemicals but could easily be adjusted for other brands.

The smaller one fits a 1/2tsp (2.5ml) spoon, which is perfect for topping off the chlorine levels.

The spoons are based on this customizer https://www.thingiverse.com/thing:682146
