Hello All,
I thought these may be of interest:
1) I was pointed to a maker (
Billie Ruben) who produces 3D Printing guides and had a feature in the
RaspberryPi mag issue 37 about how to produce similar guides. She presented on
YouTube about the process she uses to create the guides.
2) The mag can be download for free (or with donation) and had an article about an icing extruder on
kickstarter that is over 2x funded already.
