working mini roots blower

cults3d

Its been a while but i have finaly got around to getting a working roots blower finished this little guy is pretty good , and might be able to boost up to 5 hp but its untested in that application. I had a 6000kv 540 motor on it and thats too much rpm however it did make 3.5psi of boost and moved more air than any of my other air pumps/ supercharger. materials : m3x10mm : 6 m3x4mm :5 m4x10mm :2 6mm shaft( steal) approximately 70mm long pdf included. 2pc ( 4pc after an update) 626rs or zz bearings rs would be better likely. I will be working on this in the future one planned update bearings throughout, as well as a larger volume at the same diameter.https://youtu.be/JLxP3YsJAYkhttps://youtube.com/shorts/Xv4Yxew-9zc?feature=share
