Anyone who has serviced a Mini Stealthburner knows how fiddly the small parts get, and a scaled-up version makes the whole thing easier to work on. That is the angle here: an oversized take on the Mini Stealthburner toolhead, built to celebrate the launch of the Voron V0.2.
The assembly is built from giant red and black printed components, including an oversized E3D Revo Voron hotend replica. Work begins with the heat-set inserts and that anti-squish screw, seated using a soldering iron. From there the guidler arm, BMG shaft and gear come together, then the bearings, shuttle, guidler, latch and mid-body go into the main red housing with M3 screws. The main drive gear, backplate, tension thumb screw and three cooling fans follow.
Several details stand out. There is an oversized BMG gear set with dual drives, plus a giant pancake stepper motor and a printed PTFE tube secured inside the hotend mount. Dual nozzle LED boards and their wiring sit in the cooling ducts, and an oversized X-carriage mount and strain relief bracket complete the assembly. Wires are routed through channels and held with zip ties, with hex drivers and an electric screwdriver doing the build work.
One choice worth discussing is that the heat-set inserts and bolts are all printed rather than metal. That seems a fitting touch for a project this size, though I would want to know how they hold up over time. The finished toolhead rotates on a stand with the LEDs lit, and it comes out nearly as large as the V0 itself. Build information is available in the Voron V0.2 repository.
