Hotend for Bambu Lab H3C 3D Printer
Built for the filaments that fight back
Carbon fiber, glow-in-the-dark, metal fill — abrasive filaments chew through brass nozzles and take your dimensional accuracy with them. This one is hardened steel at HRC 55+, hardened through rather than coated, so the orifice holds its shape print after print. Print what you want, and stop thinking about the nozzle.


Quick Swp. Three Screws. Under a Minute
Three screws and the hotend comes off. Three screws and the next one's in. No disassembly, no downtime worth mentioning — switch to hardened steel for an abrasive job, switch back when you're done.
