This is a remix of emcee1111's transmitter box to support this USB-C based charging coil: https://www.amazon.com/dp/B09FLCMGV9. The original charging coil listed for the Wireless Bento Box doesn't appear to work well with 24v fans. Based on my testing the above charging coil works very well. The wires connecting the coil and the circuit board where a bit short so I had to add a short extensions.

This remix also includes an update to CerialPhreak's coil support, with an added retention clip to help when a USB-C cable is inserted into the port.

I recommend adding two small supports under the corners of the notches to help. The included 3MF file has these in place. The print settings are tuned for PETG due to the temperature that the coil can produce.
