Voron Stealthburner V6+Volcano Toolhead Extension Mod

A Duct-Extended v6 Printhead for the Stealthburner

The Voron Stealthburner toolhead includes a printhead module that is compatible with a standard v6 hotend. In this mod I attempted to replicate bythorsthunder's mod for the Stealthburner Rapido UHF, except using the Stealthburner v6 print head as a starting point so that the SB can now accommodate a v6 hotend that is equipped with a Volcano nozzle.

Why is this useful?

It's possible to get fully equipped v6 hotends for just a few dollars each. Their flow rate can potentially be increased by adding a Volcano nozzle and, optionally, a copper nut around the nozzle. (CNC Kitchen documented this in their Youtube video Volcano is Obsolete: Just use Nuts!) The flow rate could further be increased by using a CHT/clone Volcano nozzle, and even more so by upgrading to a Volcano-length ceramic heater. This all makes it possible to build relatively high performance SB compatible print heads on a budget.

Customizing the Duct Length

The included f360 file (inside of the .zip) has a single parameter that sets the distance to extend the ducts. Measure the distance that the nozzle's threads extend from the heat block to get a rough idea of how far you might want to extend them. In my case this was 9.5mm so the included STLs are set at that length. In one of the included screenshots I've set the nozzle extension parameter to 1000mm as an extreme example.

Modified to accommodate a v6 hotend with Volcano nozzle (or of arbitrary length.)
