This is my proposed mounting solution for the aftermarket SSR module with a low-profile heatsink for the Qidi Plus4. It replaces the factory SSR PCB using the same mounting holes. You can attach a 40x40x10mm cooling fan for extra cooling. The main plate can be connected without the fan mount if you want. I also added MG Chemicals 8618 Silicone Free Ultra Thermal Paste to the backside of the SSR.
