the first one works so I scaled it up to around 200% it’s awesome

@user_837435258

anyone know if 3d printed screws would work?

@user_837435258

Did the scaled one work?

@user_837435258

Replying to @user_837435258 :

Awsome little engine

@ben.jmarshall09

amazing print, works best when scaled up to at least 130% with the shaft’s length and width scaled down 1%. I made mine 200% with PETG translucent. with WD40 and olive oil (don’t ask why) it ran as low as 1psi and with a vacuum ran so fast i couldn’t stop it burning my fingers in the process 🤣
