GreatFET Case buttons

The GreatBox case for the GreatFET One has a small issue - the reset and DFU buttons are really hard to press.

This model adds insertable buttons which help with that:

1. Print 2 of these buttons

2. Insert them into the button holes when the GreatFET one is still outside the case

3. Insert the GreatFET one into the case.

You might need to bend the tabs a bit back so it fits, depends on your printer.
