This is a simple buildplate holder that I drew up. I just couldn't find something that looked sturdy enough and didn't have slots for each plate. The slots for each plate isn't necessary. If you want separation between each plate just use a sheet of paper. This is just something simple that holds them, some allen keys too, and without tipping over. This does the trick.
The included .stl file will print what you see in the pics. I used silk PLA with 15% infill I believe. The Fusion360 is also available for you to mix it up and change it to your liking.
