I modified the frame from thing 25444 to fit the 1/2" square wood sticks from Lowes / Home Depot, and use #4 screws to fasten.

The original Apple logo, like you have never seen before!

In the instructions, an ingenious way of getting the color layers right is explained, credits go to "zeq" for this.

I decided to revive the venerable iris box by redesigning it in OpenSCAD and making it printable with fewer parts and less assembly. It's also somewhat larger (though now the dimensions are easily adjustable with OpenSCAD), the tracks are redesigned to give more rigidity when closed, and it now opens and closes according to righty-tighty, lefty-loosey. The ring is also aesthetically redesigned and the base interior tapers down the wall thickness to give a little more internal volume.

After seeing an LED helicopter (http://www.youtube.com/watch?v=zVCxJNZLElU) I wanted to build my own. Instead of using their concept, I wanted a Maple seed design. The leaf should fly 30-40 Feet High and Spin Back to earth. This is my 4 revision and should work.

Background information about the last 3 designs:

LED Leaf V1- Smaller Area with a 5mm tall leading edge & .5mm Thick wing.
Launched well, but did not spin. Weight distribution issues.


LED Leaf V2- Same size a V4. Wing thickness .5mm leading edge 3.5mm tall.
Same problems as V1, Launched well but did not spin.

LED Leaf V3- Same size a V4. Wing thickness .25mm (1 layer) leading edge 3.5mm tall. Would spin but plastic on the wing did not stay together.

LED Leaf V3.5- Took the LED Leaf V3 and Traced the profile in paper. Removed the .25mm wing (leaving the leading edge) and super glued the paper to the plastic. LED LEAF V3.5 launched well and spun every time. 1/2 the time the LED leaf would only launch 15 feet. I think this is due to the paper wing not being supported on the tail end. When launched the tail end would cause the LED leaf to become unstable in flight. Thus making it turn and start to spin.

LED LEAF V4-
Thinner Blades with a Glue on wing

Led Leaf V5- Lightest Version yet. Best Model to print! Still can Use LED Leaf V4 PDF for the Wing.

(Large print! Not designed for Makerbot's Yet, just Repraps)

For years I wanted to print a spintop. But with the geared motor extruders this was not possible because the pointed tip while being printed would accumulate too much heat and melt away. With a geared motor you can't control the exact amount of extruded material which is just what you need to do when you want to slow down in the upper layers to give the plastic more time to cool down.

Now that we have stepper motor based extruders it's possible so I just HAD to create this object using OpenSCAD :)

The snap fit handle (needed to keep the lower part flat and printable) was inspired by the printed axis in the "Screwless Cube Gears" by emmett thingiverse.com/thing:10483
