Magnetic Enclosure Heater Mount for v400 / Delta

This is currently experimental. Looking for reviews/input. 

As a cheap & easy alternative to some of the other enclosure heater options available I decided to try an automotive heater for use with filaments that require higher ambient temps. Included both curved and flat back plates for those who prefer it. I still need to test which power supply is best for this application.

Magnets: 10x3mm

2x m3 inserts & 10mm screws

Heater (or any with this style base): https://www.amazon.com/Onamicit-Cigarette-Hand-Held-Adjustable-Rotatable/dp/B0BVDRZK81/ref=sr_1_3?crid=24WI4A6OMSYOW&keywords=car+heater&qid=1680498256&refinements=p_72%3A1248861011&rnid=1248859011&s=automotive&sprefix=car+heater%2Caps%2C183&sr=1-3

Power supply: This should work but may be low on amps (4/30/23 I can confirm that this works): https://www.amazon.com/gp/product/B01N3ASWZ0/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 

Either of these two should be plenty: https://www.amazon.com/LEDwholesalers-Power-Adapter-5-5x2-5mm-3262-12V/dp/B074GGMD5J/ref=sr_1_4?crid=2MX9DN8WA9BIN&keywords=12v+16a+power+supply&qid=1680500023&sprefix=12v+16a+power%2Caps%2C192&sr=8-4
