Anyone use 3d printed pistons or domes for mock up purposes?
I am getting ready to fianlly go through my spare engine and have cylinders that need a bore as well as what is "supposed" to be a 4mm crank.
Want to mock it up with plastic parts. set it to print a pair of pistons, the models I have set up to run are 6 hours for a high resolution print per pair.
Do not want to reinvent the wheel if someone else has already done this....
