Looking at the Spider V2 in Solidworks,

Looking at the Spider V2 in Solidworks, I don’t see the information for the MDF plate that holds the heater. Was this only on the first version? if so what is the rubber heating mat sitting on?

Underside of the aluminum heat spreader. You need to order the heater with adhesive to stick it to the aluminum.

There is no MDF insulator like HercuLien, but there could be.

@Eclsnowman Thanks. Been looking at all your builds and got confused. I forgot to include info they needed for the order , so I was able to update the requirements on the heated pad.
