Parametrised Puddle Jumper
by gringer, published
A spinning flying toy thingy.
This is a copy of thing:37110, with the hole rotated 45 degrees to avoid the need for support, and most things parametrised.
Printed on a Reprap mendel with .15 layer height and 50% fill. Use as little fill as you can handle to make this fly better.
Cut the disks from the blades (they are needed to keep it planted to the print bed).
Spin the puddle jumper between the palms with a quick motion. My cat loves chasing it around the room.
It is possible you will need to print the parts separately to avoid a blob when the printing changes from the insert and rotor to rotor alone.
