With the latest release of Repetier-Host V1.0.3 it is easier to work with different colours in a print.

@Herman_Steyn
Do you colour mix too? I have created a Gcode colour mixing script for these type of nozzles should your firmware support simultaneous multiple extruders.

Thank you Steve. I have seen your work some time ago but patiently waiting for Repetier to publish his firmware for multiple extruders running simultaneously ( https://github.com/repetier/Repetier-Firmware/issues/286 ) before I go the mixing route.

Glass is genius! And are those spokes for the rods?

@Daniel_Joyce Are you referring to the glass towers of the printer and the way the arms are connected to the effector? The connections were first introduced by Tim Jacobsen https://www.youtube.com/watch?v=RM1ytIyH6BQ&feature=youtu.be

Well the glass towers are a great idea for fighting thermal expansion. As for the arms, the string is cute, but why not use a spring in there as well?

@Daniel_Joyce Yes there is a spring in there.
