olivier.berlinOk, next try. @falko told me that I need to provide more information. I designed and built a 3D printable, working replica of the Titanic's engine from old blueprints that I found in books and on the internet. She was meant to be printed at an scale of 1:75 and run on a small compressor but I couldn't get her to run due to friction issues so I reprinted everything at a scale of 1:37 and now I can hook up my vacuum cleaner to the exhaust and she just flies.
