NES Mini Clone Raspberry Pi Conversion Useful Parts

I've recently converted one of the Chinese mini NES clones so that it now has a Raspberry Pi 3 running Retropie.

These are a few of the parts that I designed and printed to make things a little easier and neater.
They consist of:
A) A mounting bracket that ensures that the micro USB and HDMI ports on the Pi 3 line up as close as possible to the existing holes on the back of the clone case. UPDATED - Pi Mount V2 uploaded which has more material surrounding the screw holes.

B) A mounting bracket for locating 2 momentary push button switches so that the reset and on/off buttons on the clone case are fully functional.

For info on how to wire the switches and install the necessary script take a look at ElTacoLoco's excellent Thing. https://www.thingiverse.com/thing:2011955

C) A plate that can be used to mount 2 x USB sockets so that you can use USB controllers instead of the 9 pin connectors that these clones come supplied with. You will need to buy 2 x 90 degree USB extensio
