Bozzle V2 (0.5mm) Full Tungsten Carbide nozzle by Rentable socks

It's probably as close to perfection as you can get out of the standard nozzle formats. The Undertaker nozzle, but better.
•0.5mm aperture less likely to clog with fiber-filled engineering filaments
•Very little compromise on achievable detail
•CHT-like flow without obstructing path or complicating cold pulls
•Brass-like thermal characteristics
•Standard length melt zone for very slow work and standard retractions
•Still volcano compatible with an extension adapter if needed
•Will most likely never need to be replaced

This provides a significant and immediately recognizable increase to maximum flow rate. I believe my extruder is now the only limiting factor of my spaghetti output.
