So i felt the need to own a Dremel. Bought one. Started to create a first prototype in plastic. I’m pretty sure I need another material for the real thing though. I googled polystyrene and it’s melting point is 240-260 ‘c. I used my multimeter with the temp-sensor to measure the temp of the tip of my soldering iron. Got about 70-110. Tried to apply some of that heat for a couple of seconds. It melted. And it also melted some during drilling. Making a mess out of my drill. So maybe it’s not polystyrene plastic or my reasoning is flaud. I will look for another material with better heat resistance. How about some kind of metal perhaps?
