@N33R@fops.cloud maybe i could try partially coating an aluminum or mild steel screw instead of using solid zirconia. itd be disappointing for me personally to not use solid fucking zirconia but a thermal barrier coating would still be very helpful and itd let me thicken up the inner screw to achieve an interference fit @snacks@netzsphaere.xyz i might be cooking tbh. thicken up half of it with a zirconia-based tbc and the other half with copper plating
