This is a remix from the site I provided at the bottom of this description. I remixed this, because the original version was too tippy with the console sitting unplugged. I added 1" wings to each side of the backplate. I also rounded all edges so the finish came out nicer. I manually added support material when I printed it and have removed the supports so it can be adjusted to your needs. Each part is individually layed out so they can be removed if anything needs to be adjusted. Ensure the supports are stopped before it gets to the round pin hole of the backplate. If you do not stop the supports, you will have to drill the hole to remove the support material and remove supports from the kickstand clip on the backplate.

The backplate will NOT PRINT WITHOUT SUPPORT MATERIAL! Adding a brim to the round pin will be required otherwise you can plan for it coming loose.
