Micro Swiss FlowTech Hotend for Bambu Lab X1 / X1C with Bondtech CHT

The Micro Swiss FlowTech hotend for Bambu Lab X1 and X1C is a drop-in, all-metal upgrade made in the USA, supplied here with a Bondtech CHT high-flow CM2 hardened-tip nozzle. Installation is plug-and-play, with a heater core and heatsink made for X1-series printers. The nozzle and thermal break are a permanently sealed assembly for leak-proof performance, and nozzles can be changed cold, with one hand. Official CHT flow is up to 50 mm³/sec, with more uniform layer deposition from Bondtech's multi-chamber melt path. The kit includes the X1 heater core, heatsink, two titanium mounting screws, a 0.4 mm FlowTech CM2 CHT nozzle, a silicone sock, two fan mounting shoulder screws, and a printed nozzle-changing tool.
