Zen Kinetic Art Wind Spinner with magnetic bearing

prusaprinters

The flowering plant-style design spins with a slight breeze.  The model has smooth movement with very little resistance to spin using magnetic bearing. All parts were printed without support.Non-printed parts:    One copper penny for the bottom of the magnetic assembly    One 3" Screw x 1/8" diameter 32 thread pitch    One 17 x 1 ¼" stainless brad nail (Hillman 532672)     3 - M3 4mm screws     27 Neodymium Magnets 10mm x 2.5mm round with 3 mm hole (50pack $8 at amazon https://www.amazon.com/gp/product/B09ZLFNZ4S ) All magnets face the same direction both in the housing and the spinning section.  The ones I used are beveled for a screw on one side, so easy to tell the polarization.  The brad nail head is ground down and both sides are sharpened.  There are 3 rows of magnets in the magnet body housing.  Magnets on the spinning part are adjusted with the plastic nuts.  Each set of 3 should be just below the level of the matching magnet row in the main body.  The nut with the brad nail can also be turned to raise and lower the entire spinning assembly for desired clearance.
