I am building a static structure where I need to connect two parts together with the following constraints (please refer image): The top part (as in the image) reaches temperatures of about 70-80 degrees celsius. This is to be connected to a load cell. Load cells are highly sensitive to temperature. So I need to put some insulating components between the top part and the load cell. The connecting part will experience forces in the range of 10-20 kg. Dimension of top part = 15 cm in length.
What materials can do this job? The material needs to have the following properties: Bad conductor of heat. Structurally strong enough to sustain the loads mentioned.
The material should also be easily available and not too expensive. Should either be easily able to cut or be 3D printed (on a normal plastic 3D printer).
