Hobby Paint Rack Diameter Reducing Collar FDM 3D print

Figuring out how to describe this is harder than I thought. If anyone has any ideas let me know!

A 3D printed collar inserted into a paint rack with 1.37" diameter holes so that 1" diameter paint pots don't tip over or fall out.

I bought a paint rack to hold all my hobby paints, I use Pro Acryl, Tamiya, Vallejo, Army Painter, and Reaper paints. I decided to buy a paint rack to clean up my hobby desk.
As I've increased my paint collection I have bought many more Vallejo and Army Painter paints than expected and must use my larger diameter paint rack positions to store them. I kept knocking them down and they all sat at tilted angles just about ready to tip over and fall on my desk!

I didn't want to buy another rack so I designed and printed a collar that fits in the 1.37" hole to securely hold a 1" paint pot.

This maximizes modularity as it's only one collar for one hole.

Since I've made a bunch of these I've discovered I really like them! They have an added bonus: with just a little more distance between my paint pots it has increased visibility and ease of grabbing.
