This was my first attempt at a modular usb storage. My HexDeck model is better but some may still prefer this over that. The connector here isn't the best though.

Disclaimer:

This usbs tolerance is a bit tighter to prevent taller sticks from falling. Please don't try to force the usbs in, since it could potentially damage the drive when taking it back out. This may occur since everyone has slightly different settings and filaments. If it is a bit hard to fit the usbs in, maybe sand down the sides a bit to make it easier(wasn't necessary for me)
