OZO FFT1625

This is an attempt at a case for a digital clock soldering kit which I think is not really sold anymore. The PCB states "OZO FFT1625" but I think it was sold under the name "DIY FFT1625".

Since I don't think I'll improve the design I uploaded the step and f3d files.

Things to do:
- Enlarge heat-set insert holes
- Thicken the backside of the heat-set inserts
- Make the shadowline at the front smaller
- Shift the usb cable hole to the front
