Optical Illusion Pinwheel with Bearings and High Quality Mesh

Banana not included. This is a pinwheel with two opposing sides that spin in opposite directions.

Inspired by the one by Dalpek, I made a new one with some improvements:

• Embedded bearings
• Mesh is higher quality (no polygons visible)
• Size is more reasonable – the original seemed wastefully large
• Handles are separate so you can print two sides without supports and glue them together

Items Needed

• 2 bearings of size 695 (search for 695RS or 695ZZ on your local online markets).  They are readily available worldwide and cost pennies.  The dimensions are 5x13x4mm. 
• Superglue
• Electrical tape (optional)

Instructions

• Print A and B versions of the propellers.  I recommend something soft like TPU.  DO NOT print one of them twice; they are different. 
• Do an M600 “color change” or a pause print right before the bearing enclosure is printed over. (Around 7.75 mm height)
• Insert the bearings.  They should fall in place nicely.  If there is some sideways slack space, I recomment wrapping the bearing with electrical tape to make it snug.  (just cut off the excess from the top/bottom.  Make sure it falls in fully and nothing is poking out the top for the nozzle to crash into.
• Print handles and glue them together.  Optionally change colors after 1mm to get the text to pop out.
• Handle should snap into propeller bearings snugly, but feel free to add a tiny bit of superglue to prevent it moving.  Just don't glue the bearings shut (lol)

I included the source in case you want to modify it or if you're a monster who wants to remove my name from the handle (how dare you).
