Simple Sandisk USB Case
This is a very minimalist and tiny usb case for the legendary Sandisk Cruzer Blade 32gb usb drive, they're about $7 and if you get the chip out of it as seen in the pictures, then it just slots into the 3d printed case. Very simple print as well, I recommend using two colours, it fits on your keys really well, you won't notice it and slots into the actual port very satisfyingly too. If you prefer the bulkier, sliding usb design as seen in the last photo, then go check out my profile or the link here: https://makerworld.com/en/models/1183776-sliding-sandisk-usb-replacement-case#profileId-1194426
