My first model ;)
SD cards holder to keep your desktop organized.
Small sized it can hold 6 cards.
After unsuccessful tries to print SD cards holder, I decided to design my own model. My motivation was to have a simple model using a minimum of plastic.
The card doesn't stick tightly in the slot because I wanted to be able to remove it easily. The dimensions give a margin of error for the less accurate printers like mine with a 0.5mm nozzle and 0.4mm layer height.
Bottom depth: 3mm
Slot spacers: 3mm
