Professional painter and propmaker
I bet a larger version would work out perfectly! I've actually done some in specific dimensions for vending machines and also top-loading coolers.
My main concern is somebody using the image to misrepresent their product. It happened all the time with the custom Nerf blasters. I don't like the watermark either, but I doubt anyone was going to download it for wallpaper, lol
I appreciate you making it worth sharing, thank you too! I hope you'll have a great time with them and just expect the first few to be tests!
