At HackFFM we are currently working on a similar design. It already works and weighs about the same. The problem ist that like this one it needs a closed loop controller, so it is not a drop in replacement.
With standard parts and a NEMA 14 i got a direct extruder down to 240g

Yes, it's M8 threaded rod. The machine is planned as a real RepRap with very basic parts that are easy and cheap to source. The mechanical design is nearly finished, i am in the process of going over all printed parts for optimization and some smaller adjustments. Once that is done a second prototype will be built and tested. After that the final BOM is compiled.Quote

I have noticed threaded rod on your Z or am I mistaking?

It's your thread, push it in any direction you likeQuote

I like it. Skimmed through your blog for a little, I also like the silicone heater block cover. I wonder what is the temperature on the top of the slilicone after a few hours of use. Do you happen to have a heat measuring gun that can be used for this?
I'm sorry to go off track with this but I am really curious. Completely covering the nozzle in silicone would help with fan funnels that can be brought much closer now that melting is not an issue like with completely exposed heater block.

50C is a good value considering that in a closed enclosure the internal temp would be about as much (maybe even 60C).Quote

I haven't measured the temperature, but it is always in a range where i can safely touch the block for a short moment, so i would expect <50C

Very interesting. I am surprised that people still have some interest in light-weight designs. When I produced a 13 gram J-Head hot-end, there wasn't much interest.

If that's a cheap, brush type motor from a toy, it won't last long in a 3D printer.
Here's a stratasys extruder without the hot-end:

Speed is still one of the biggest limiting factors for mass adoption of 3D printers and unless we can print a medium size, medium complexity part in a few hours we will remain enthusiasts thinkering around with this hobby. Some might have built businesses around it but that is a different situation. Did you improve your design over time or did you move over it? Maybe now would be a good time to revive it . I am trying for some time to talk about an induction pen-like hotend but my skills don't help me prototype such thing
