This is a custom holder for the Chemical Guys 16 oz. spray bottle from Amazon for 91% IPA (non-affiliate link: https://www.amazon.com/gp/product/B00ABYVT64).

I decided to organize my 3D printing tools using Gridfinity by Zach Freedman and could not find a holder for this size spray bottle.

I liked @AsylumLife's design, but none of the sizes fit this bottle. I made the opening 64mm, which allows a nice fit.
