<p>We are trying to repair an Ultimaker Original+. One problem is a missing resistor isolation. The Ultimaker Original+ prints with up to 260 Degree Celcius.</p>

<p><strong>Which kind of isolation products are suitable to resist the heat and are fitting on the thin wires of the thermistor?</strong></p>
