A few years ago my grandma started using a nebulizer for her asthma, and her supplies were always scattered around — vials everywhere. I looked online for something to keep it all organized and couldn't find anything, so using some CAD and 3D printing I made her a solution. Now everything has its spot, laid out by day and time, so it's easy to see at a glance and stays tidy. Some friends of hers saw it and wanted their own — and I thought, I might have something here. I put it on my website and Etsy, and it's been a reliable seller ever since.
