This is a remixed version of the paint pot holder by @Slanjonok that is designed to fit citadel paint pots. I modified the RAW files found on their page https://cults3d.com/en/3d-model/art/improved-jet-another-vallejo-paint-holder-standalone-version-4x4 as I had issues printing directly.
I tried to just use the settings from the original Vallejo holder for this but it spaghettied so I made a couple of modifications to get it to print.
