Description
Print your own US Flag keychain fob.
This print is intended for printing with a printer which supports "pause @ Z position".
This keychain was inspired by Jetty's Canadian flag keychain fob, Thing #26139,
thingiverse.com/thing:26139
Update: and, it turns out, Jetty just published a US flag fob as well (but I scooped Jetty :)

P.S. Feel free to figure out the cut depths for the keys. They're not for my house or jet plane.

Instructions
0. Slice the us-flag STL with a 0.3 mm layer height.
1. Print he first layer using white or natural uncolored ABS.
2. As the first layer is printing, note the Z height of the print head. Call this height Z0
3. Enable the "pause @ zpos" function. Set the pause to be at Z0 + 6*0.3 = Z0 + 1.8.
4. When the printer pauses, switch to a blue colored filament.
5. Resume the printing.
6. Again, enable the "pause @ zpos" function. Set the pause to be at Z0 + 8*0.3 = Z0 + 2.4.
7. When the printer pauses, switch to a red colored filament.
In the above calculations, the 0.3 is the layer height which was used in the OpenSCAD model. If you want to use a different layer height, then edit the OpenSCAD model changing the value of the "l_h" parameter to the layer height which you wish to use. Then render the keychain and export a new STL file.

Awww, I saw the pic and was going to use http://www.thingiverse.com/thi... to post a derivative titled "dnewman's keys!" but it looks like you already thought of that
:)
Might have been interesting: the Kwikset key was actually punched on a Blue Punch that was set up for Schlage cuts. The other key is an Ilco knockoff of a "reserved" Russwin keyway (if I recall correctly).
And thanks for mentioning 8925: I had thought once or twice about doing similar but hadn't yet looked to see if it was already done. (And no need to actually get one's hands dirty measuring keyways: HPC actually publishes the dimensions for many keyways as well as cut depths and angles. Or at le
ast they used to.)
