Modular Desk Organizer

Here is a simple desk organizer. It can store 3 SD cards and 3 USB keys + post-it notes of two different sizes (< 4cm and < 7,4cm) + two pens and two markers + a tray with a ruler slot.

The files are available in one file per compartment or for the whole organizer in one file.
No support is needed and you can use a rather low resolution (in my case 0.2), the parts being simple.

Personally, I printed the pieces one by one and then pasted them together.
