Ink Peg PLA Injector - Quick Colour change
thingiverse
This second generation Inker will allow quick colour changes of your natural PLA, without the need for complicated mulitple extruders or changing over PLA reels. Instructions 1) Print out 2 of the STL file 2) Attach the sides to a peg 3) Cut a bit of kitchen sink sponge and put a bit in both sides. 4) Fill sponge with ink, I found the best ink is the printer ink. 5) Make a few of these with different colour mixes. 6) Clip the colour you want to the filament above the extruder then print away in colour.
