Tesla cup holders have always been quite large and therefor you need an extra cup holder adapter to make cans fit which you don't want to spill.
This cup holder adapter is designed for skinny 330ml cans as i could only find adapters for fat 330ml cans i decided to design this one as most cans i drink from are skinny.
If you like this design you might like this one which is modular for both Skinny and Fat 330ml cans, similar design but an adapter is removed from the middle if you need for fat 330ml and added back to use for skinny 330ml: https://makerworld.com/en/models/23536#profileId-21062
