The Colouriser

Hi.
This is my version of a filament colouriser. Works well with PLA, (I don't have ABS) The idea is to be able to colour individual segments of the filament strand to give a stripy effect. To use is simple. Just feed the filament through and colour away till your hearts content. Use as many colours as you want. Though I have only used it for my 3D pen I guess it will work with a printer as well..... I haven't tried that yet. You could 'colour as you go', Anyway I hope some finds it useful. Thanks for looking.
