    I have moved to PETG from PLA... PLA has a bad habit of drooping while sitting in the bed of my pickup truck on a hot summer day, the interior temp of the truck will get near to the temp at which PLA starts to get spongy... its "Glass Transition Temp" is too low. you can get higher temp PLA, but PETG is cheaper, and outside of its higher "Glass Transition Temp", it basically works the same as PLA.

    as to 3d printing topics pertinent to model submarines... I have downloaded and tested a few STL files for peristaltic pumps... there is one on thingiverse that uses ball bearings as the part that puts pressure against the tubing, and it works quite well.

    cheers tsenecal,

    will look into PETG. i saw them pumps and wondered how good they would be. also seen a type 21 hull that you can print too which i will give a go at soon.
