Assembly:

Power off your printer and disconnect the power cord!

Take off the backplate.

Run a wire from the printer PSU to your buck converter and adjust it to 12V output.

Take the 12V wire an run in up the printer (rear left)

Assemble the four frame pieces. Do not insert the top magnets yet.

For the assembly and light please refer to the original model.

All the fans have to be connected in parallel.

Run the wire from the rear left corner (where the hole is) all the way around. 

It worked best for me by opening little gaps in the inulation with a wire stripper and solder the wires to the magnets to it.

Wire the magnets as follows on both sides: (the longer side is positive)

Since magnets loose their strength when heated I do not recommend soldering the wire to the magnets. 

Just remove some insulation from the wire and press the magnets onto it. Like this:

Afterwards you can remove the excess wire.

Assembly of the Fan module:

Connect the magnets with a wire using the same process as shown above. (the longer side is positive)

Put in the 8 threaded inserts.

Screw the fans on the Fan module with the shorter screws.

Connect the two fans to the Y-Splitter cut off the female plug and solder it to the wires coming from the magnets. 

Do some cable management and youll be able to fit the FanCover onto it. Use the 4 longer screws to screw it together.

Assembly of the button:

Please refer to the link above for the installation of the button.

There is a hole on the bottom where you can also insert a M3 threaded insert to mount it to the frame.

You can use the hole in the FrontRight Frame piece to run the wire up to the cable canal.

Assembly of the Side Cover Holder:

Put the magnets into the holes.

Screw the Side Cover Holder and the Side Cover Spacer to the side of your top riser using M3x30mm screws.
