I want to get a 3D-machine which errect the www.jovoto.com https://www.jovoto.com/projects/300house/ideas
                                         IPOD https://www.jovoto.com/projects/300house/ideas/12491

This is a update on my 3D Printer extruder/heater controller test run:

I have to update my heating tip, this was a 4mm tip from a 1/4 bolt.

I have brass I can machine and 3mm drill bit.

This is my extruder super high temperature tip design for plastic or liquid metal.

Hi Tommey. I like the idea of using a sparkplug. Did you say that drilled the hole 6 mm or .6 mm? I use .16 mm in my (used a carbide pcb bit); how well would that drill?
