Model origin

The author remixed this model.

Differences of the remix compared to the original

Changed the model only to use magnets instead of screws. As well integrated a Pi Pico with two Sensors that are controlling the fan speed then. Support for the Screen has been removed.

Additionally remixed a wireless power module receiver, so no Power Cable needs to be routed inside the printer but use a sender from below the bottom plate. Power supply to this sender is coming from the original Bambu Power Supply using a buck converter 24V to 5V. Cable is routed then coming thru a Cable Guide opening.

The base is remove-able, so it also works without wireless power. 

Magnets in the rear wall do not work since the cover sheet is made from Al. Therefore a VHB tape is necessary to avoid the bed crashing into the filter. The Lidar bracket passes quite close to the filter cartridges.

All of this components are not created by myself, nor did I create the software for the pi. Therefore all the credits go to the original creators and especially CRYD for the detailed instructions.
