M.2 2230 SSD Organizer (stackable)
edited my previous one so it's 2230 and not 2280.
Dells have started to ship with a lot more 2230 SSDs, so we'll be needing to store those as well!
Edit: took my own advice and changed the spacing for the slots from 2.4 to 2
I recommend printing with a brim. The example print is in white SUNLU PETG.
