I saw several models that included RSA tokens or that only held one or two id's, but none that held 4+ and did NOT have the RSA space on the back. I designed this one using OpenSCAD so it could be adjusted for however many id's you need. I selfishly designed it for myself as I needed it to hold 5, but then I realized others could use it too!

I also included some area at the bottom so you can easily put some text there (at least I could with Bambu Slicer) for your organization.

I printed it with the base down even though it was angled and it worked best. Trying to print on back doesnt work as overhangs are too big and not really a good way to do supports int here.

I would do ABS or PLA ( I did both) - PETG failed miserably with it.
