This thing is an extruder motor 'windmill' using Slice Engineering's official graphics files. It is intended for personal, non-commercial use. Enjoy.

In addition to windmill parts:

• 8mm diameter x 3mm tall magnet
• Crazy glue of some type
• Printed magnet aligner ('MagAlign' included here)

Printing:

• First layer, set up extruders to print the letters and logo first, then the disc
• Best on flat print bed, not textured
• If printing MagAlign piece at same time, use disc color/extruder
• The 'e' is a separate file as I had to kern the 'ce' manually to match the logo
• Place all disc objects in slicer then rotate 180 degrees x or y to print
• Magnet alignment tool can be placed and printed as-is

Assembly:

• Place MagAlign on surface with spokes down
• Press in magnet in center circle flush with surface
• Magnet should stick up inside about 2mm
• Place windmill disc face down on surface
• Flip over MagAlign and pre-fit over disc, then remove
• Apply a small drop of glue to center of raised part on disc
• Place/Press MagAlign w/magnet onto disc
• Let dry according to glue directions
• Remove MagAlign and place windmill on extruder
