Jerrill Johnson is an excellent example of what a determined maker can achieve. In the video below he demonstrates how he makes 3d Printer Nozzles from Acorn nuts.
He uses a drill, Dremel rotary tool ,very fine drill bits and a few loose bits to make the parts.
Jerrill has also added his custom tools to Thingiverse so you can print them off for making your own nozzles.
Excellent!
Thank you for the mention! I also have nozzles for sale at http://www.jerrill.com that are made using the process described on Thingiverse and in the YouTube video.
Thanks @jerrill you have done an amazing job!!! Nothing like hand made perfection…
