The main improvements of the Snappy 3 over the old Snappy 1.1 are:
- Replaced the old metal lifter rod vitamins with printed equivalents.
- Bed leveling is now adjustable.
- Z axis homing is now towards Z-min.
- The herringbone gears and racks should be smoother and cause less print artifacting.
- The extrusion bridge is now lighter.
- Tightening the extrusion idler is now done with a printed adjustment screw.
