Made myself something to store the usb adaptor that came with the printer to have it always at hand.
Made a snap on like the original spool holder. It was two slots for sd cards just in case it's useful for an extra card.
It's for a Anycubic Kobra 2, but probably works for other similar models.

Feel free to remix, change, whatever and share...
.step file and .f3d file included.
