The Gen2 model is a natural evolution from where we started, and has improvements in many areas:

1.   All plastic parts for the housing are made from AntiStatic Plastic (in Gen1, only some where)
2.  The internal motor/tube housing has significant improvements including being 3D SLS printed by the Danish Technology Institute.
     It is now 90% nylon dust and 10% steel dust to make it much stronger and able to be printed to tighter tolerances.
     Some design changes include the bearing holes being reduced to decrease possible wobble in the bulk tube.
3.  The Vibrating tube is now CNC machined Aluminum
4.  The Motor Window and Powder Exit/Drain parts are also now molded instead of 3D printed.
