Anycubic i3 Mega Pro (S) internal Pi Zero 2W mount with external SD card access

This is an internal bracket for the Anycubic i3 Mega Pro that replaces the existing SD card reader with a mount for a Zero 2W formfactor SBC (Rasberry/Orange/Banana, etc.), allowing the Pi's microSD card to be accessible from outside (for when your Pi inevitably corrupts it's SD card).  Additionally, there is a antenna holder for SBC's that come with an antenna (i.e., Orange Pi) and a mount point for a TXS0108E logic level shifter if you are contemplating using UART3 for Klipper communication like I did.

Print in just about anything, I used PLA. If you don't have an Orange Pi Zero 2w like I do, then you likely don't have an external antenna and can omit the holder from your BOM.

Installation:

1. Remove the existing SD card reader and ribbon cable, save the screws
2. Attach the Pi to the bracket using 4 M2x4mm screws. they should just self tap
3. Optionally, attach your TXS0108E using 2 M2x4mm screws
4. Optionally, install the antenna bracket by slipping the antenna inside (should snap in easily), then mount to the side of the bracket by sliding the notch over the edge and then securing with a M2 grub screw (or socket head, shouldn't really matter).
5. Connect your GPIO and TXS0108E connections (assuming you are using GPIO) now, as you won't really be able to once it's installed. If you're just using the USB ports, then make sure the antenna holder is not obscuring them and re-position if you are also using that.
6. Using the original 4 screws, mount the bracket in your machine.

NOTE: The last three pictures showing the Pi and TXS0108E mounted and wired up temporarily is from an older prototype board, so don't think there is yet another part floating out there to print due to that picture. I just wanted to show what that looked like.
