[BETA] Neptune 4 Plus chamber heater

This is a work in progress chamber heater for the Neptune 4 Plus.  This will allow you to print materials that require high chamber tempereatures even with a bad enclosure/none, the way it works, is that the air that exits the heater can get upwards of 120°C while a badly insulated chamber reaches around 65°C. To control this you will need to add some lines to the printer.cfg. You will also need at least one but optimally two thermistor ports empty as well as a heater port

Disclaimer I'm not an electrical engineer, DO NOT play around with mains if you are not 100% sure you're able to.

• 3 walls

• no supports

As for print materials the more heat resistan the better. The glass transition temperature of the plastic has to be above the bed temperature or else it will sag down. 

PLA and PETG not recommended, print at least out of ASA/ABS

Parts that are reused from the original aux fan:

• Fan splitter board

• 2x6025 24V radial fans

I haven't printed this version yet, but it incorporates a lot of fixes compared to older versions. So knowing this, measure everything. I could adapt the design for N4, N4pro and N4 max if interest arises.
