Great initiative! However, I would put the mounting plate further away from the nozzle.
Maybe there are easily-available heater blocks, I can imagine that finding a good heater block may be the most difficult part of your design.
Also, it doesn't have to be that long, I think you can get away with a shorter barrel. I am using a 30mm fan to cool things down, looks like yours is also 30mm?
Good luck with your development!

I'm thinking of soldering a brass tube to the inside of the top cap once the push connector threads are tapped because the inner diameter of the threaded sections is quite large. Thanks for the dimensions.

Nice work it's good to see somebody able to think on their feet and be a good fabricator and use what's available don't get discouraged if at first it doesn't perform well as you like. I don't think anybody's put together a hot end that worked first time even fancy engineers that crunch all the numbers. You have to do a lot of testing and speaking from experience as I have designed and built one myself to good luckQuote

A little more work was done on this - the cap nut was filed using a drill press to a cone with ~2mm diameter flat tip, a brass tube was cut to length and one end tapped to thread onto the inside end of the push connector threads, the brass tube was lined with a slighly longer teflon tube that ends just above the inside of the nozzle, and the brass connectors were drilled for ventilation around the interior brass/teflon tubes. A heater block was cut from scrap aluminum and drilled for the nozzle shaft and heater cartridge along with splitting the side and tapping a tab to allow clamping the cartridge. I'm waiting for a carbide bit set to drill the nozzle and then will set up the controller and see what happens.

i would switch out that brass tube that is over the tubing and make it stainless steel for strength.

Um, what? WordPress is web software. It's platform agnostic (at least on the user's end - I've only every tried to run it on a Linux server. Apparently it will run on a Windows server too though.) You can set up a free blog at wordpress.com, or host a WordPress install yourself on your own site/server, like I do. WordPress is very easy to use.Quote
