I created these parts to make a educational model of a oil processing pipe line. The parts slot into each other and you print whatever you need for your model. The parts should be fairly easy to print even on cheap printers.
Overview and Background
These modular piping elements can be mixed and matched for your own project
For display purposes only, these pipes and flanges can not be used for any liquids.
Lesson Plan and Activity
Print the parts you need and build your own display model
