Ender 5 Plus BTT Octopus + MOSFET Mounting Adapter

You need some shorter M3 screws to mount everything. I recommend using the original scews to mount the adapter.

You need a File or a Dremel to enlarge the original USB hole to fit for the USB-C of the Octopus board. Its also possible to make holes for the SDCard and other connectors.

There are two extra holes on the mount (left top and right top) where you can screw in the two extra support cylinders to give the board even more stability. There is an extra STL for the cylinder, you have to print it twice. These extra cylinders can be glued to the case if wanted, but thats optional.
