Some students forget the USB drives with their homework a bit too often and some teachers have a somewhat special sense of humor, so their forgetful students are condemned to use the "Stick of Shame" until the next class :)

It's modeled for _Intenso Rainbow Line_ drives, so print the test piece first, to check, if your drive will fit as well.

I recommend adding a pause to insert the board.

The dimensions are 220×18×10 mm.

**Work in progress!**
