USB-C Adapter Stand

Our students' laptops have only USB-C ports but so many of our accessories still use USB-A. So I keep a class set for them to use during our projects. I created this stand/organizer to keep them nice and tidy and easy to see when one has not been returned to me! The stand's dimensions are 100 x 44 x 33m. The adapter in use is the Nonda USB-C to USB 3.0 Adapter, purchased on Amazon. Their dimensions are 25.3 x 16.5 x 7.3mm. Each hole in the stand measures approximately 10 x 17.6 x 8.2mm. The adapters fill nicely but not tightly so they stay in when jostled but come out easily.
