Thanks for sharing your design! Nice hotend! I like very much the integrated fan duct...
On my previous DIY printer, I used a FNU hotend, which was made in one part, nozzle + looong heat-break, so it couldn't clog at all.

I also designed an extruder using Bondtech double-gear, and both were working really great for more than 3 years, without any maintenance.
Anyway, for this new design, I think I will first try the version without PTFE, and enlarge the hole to add one if it does not work well. I received my Rapido hotend: I will open it to see how they deal with the heatbreak/heatsink joint...
