Quick and dirty Wanhao Duplicator 4 Extruder Clip for Palette 2. I used the top portion of the Mosaic provided part and just did a quick mashup for the bottom portion.
I have not thoroughly tested this, but it fits perfect on my printer and uses the supplied grommet. Let me know if you make one of these and how it works out for you.
Should also work with other MK10 or MK9 extruder printers like Flashforge PowerSpec and MakerBot Replicator 1 but I have not tested it with these printers.
