Maybe some of you remember my compressor wheel?https://www.youmagine.com/designs/compressor-wheelNice to print but pretty much useless without a casing. So... I made a casing.All you need is a motor and a battery. The backplate is designed to match a motor from an 1:18 model car (LRP Fusion Micro Modified 370). Hook it up to a battery and enjoy fresh, compressed air.The compressor wheel has to spin clockwise.Here is a video showing the compressor at work:http://youtu.be/LF_rRPDeT54
