I hesitate to write about this. I do not intend to blow my own trumpet.
As someone wrote previously, PP is the best material for your purpose. But PP filament has the issue, big CTE. We, NANODAX , has announced glass wool filled PP filament which is really usable.

• Surface is very smooth.
• Easy to cut, shave the model.
• Has flexibility and strength.
• Water tight wall.
• Light.
• No odor during process.
• Endure 120-130 degree.
• Chemical resistance
• Parameter tolerance is large

This link to Z-temp forum is good to understand how it behave.
The filament is going to be put into market end of SEP if everything goes well.
