Print three part separately and glue them together.
I used PLA, my heater is only set to around 30C and it is attached to the intake side so should not be a problem. The printed model on the photo has a higher extruded grid, but that made it difficult to attach to the base.
Other parts:
This is my first model created with onshape and my first uploaded model, any feedback is welcome! :)
The author remixed this model.
Uses the linked TISKEN base model, other parts are my design.
