This is a very easy to use holder for external driver breakout boards. In case the integrated drivers on your board have been blown, you can replace it with an external driver. Use this board to hold and organize them.
It can be printed with your favorite material.
The holder can be fixed on your frame using some longer M3 screws on 3 places. Use a M3 screw with a washer to hold the driver on the side it hasn't a hole.
Alternatively you could use some doubled-sided tape.
