I built a self sourced Voron Trident 250 and instead of using the spec'd AC Aluminium heatbed setup, I use a 250x250 PCB heatbed from Aliexpress. The mounting holes are different so I printed a bracket in ABS to cater for the different hole positions.
I've printed using these bracket with a 100°C bed temperature in an enclosure that reaches ~55°C.
It held up well so far, but I will eventually replace it with a metal bracket when I find one. Until then, I keep spares just in case it fails. I would HIGHLY recommend printing it in ABS or a better heat resistant / rigid material.
