Exact dimensions

Measured 6mm exactly with calipers. Fits tight into the heater block as it should.

Solves clogging issues

Stainless steel conducts heat less than brass which helped reduce heat creep on my PLA prints.

Good quality steel

Works well for my all-metal hotend conversion. Shipping took a bit longer than expected though.
