Geetech i3 Pro B mount for e3D customizable extruder

This is a bracket designed to fit https://www.thingiverse.com/thing:1383913 to a stock X carriage on a Geeetech i3 Pro B with a metal X carriage. It *may* also work on other Geeetech printers, if it works for you, please leave a comment to let others know!

Full OpenSCAD source is included with this thing, but it is a bit hacky.

This bracket was designed to be affixed with M3x8mm screws, but M3x10mm screws will probably also work.
