ZWO Guidescope 30mm Dew Heater

A simple dew heater for ZWO Guidescope 30mm.
Necessary additional parts:

• resistive cable -> I used 1 m of a resistive cable (~35 ohms/m for 12V power supply - draws about 0.3A) wound on the inner part,
• DC connector with the connecting cable -> I used DC 2.1/5.5 barrel plug to fit the socket on the ZWO AsiAir computer.

Printing:

• I used PLA Matte from BambuLab. PLA works fine since the aim of the device is to add several Celcius when it is cold outside. In the operational scenario, the device's temperature is way below the point of PLA deformation.
• no supports necessary.
