Vacuum Engine

 

This is one of the best Vacuum engine models there is on the platform! This thing absolutely rips and works great. 

 

I find that the 3 bladed turbine works the best, but I included several different types of turbines, because if you're like me, you like to test things out and experiment. There are also a 36mm and a 35 mm vacuum adapter.

 

I printed this at a .2 mm layer height and it worked great, including the throttle lever. PLA will also work fine, I have not had issues with melting. You may have to sand the back of the lid in order to make the holes line up better.

 

EXTRA PARTS: You will need a Iego axle that is at least 40mm, but I recommend longer that that. You will also need a hair tie or rubber band for the throttle return. You also may need Iego spacers to help keep the axle in place, but they technically aren't necessary. A tire is a fun thing to put on the output Iego axle, but obviously isn't required.

Boost MeI am saving up points to get a Bambu Labs printer! This was a tricky Model so any boosts are much appreciated!
