Wil Wheaton said 'Make it so' and the internet obliged.

Open it in the Customizer App and you can generate your own!
Customize the text you want to appear on the handle.
Customize the diameter of the tap you're going to attach the handle too.
Customize how large the handle should be.

Uses the OpenSCAD write library from here. http://www.thingiverse.com/thing:16193

Updated to be more printable. Letters are inlaid into the handle and there is some built in smoothing to actually be able to print this.

Full source code at github. I will make this work with the customizer app soon.

If you want to run this just from the thingiverse files you need to download all the files for this thing AND setup write.scad (see the thing I derived from). In order for customizer to work I had to remove write.scad

Write.scad needs to go in a write folder and Letters.dxf should remain with your handle.scad
