Compact planetary reducer/gearbox NEMA17

This remix fixes some interferences and changes the bearing to a 10 outer diam and 5 inner diam ZZ I also shortened the housing so the bearing would engage the short shaft nema17 motors available from MPJA.com that are a steal. 35352 MS "3 piece starter set for 3d printing" $20 plus shipping. I used paste wax for lube as it lasts a long time and does not attract dust or other abrasives.
