LH Stinger 24v 200mm Polyimide Heater

24V polyimide bed heat for the 200mm LH Stinger setup. This RaccoonWorks x dfh.fm flex PCB heater is an adhesive-backed replacement or upgrade for the LH Stinger's lightweight bed assembly, with power leads already soldered so you are not starting from bare flex PCB.

Why this over the stock heater?

• More heating headroom: the official LH Stinger heater design is 216W at 25°C (±10%); this dfh/RaccoonWorks unit is specified as capable of up to 250W in the same 200mm-class bed footprint.
• Lightweight flex construction: the polyimide flex PCB base keeps bed mass down for a high-speed Cartesian/bed-slinger build.
• Adhesive-backed install: supplied with 3M adhesive for bonding to the bed plate.
• Built for the Stinger: sized for the LH Stinger 200mm bed layout rather than a generic silicone heater pad.

Specifications

• Fitment: LH Stinger 200mm bed configuration
• Voltage: 24V DC
• Heater style: polyimide / PI flexible PCB bed heater
• Official design reference: 2.66Ω at 25°C, 216W at 25°C (±10%), 1oz copper
• dfh/RaccoonWorks output spec: up to 250W
• Adhesive: 3M-backed
• Included: one heater with pre-soldered power leads

Fitment and paired parts

• For the 200mm bed assembly, pair it with the LH Stinger Carbon Fiber Bed.
• Building the machine from parts? The LH Stinger Starter Kit covers the broader printer platform.
• If your build needs detachable bed-power wiring, add an XT60 connector pair and wire/fuse it for your actual heater current.

Gotchas

• Heater only: this is not a complete bed plate, carriage, PSU, or controller.
• 24V DC only: do not run this from mains power. Use appropriate fusing, wire gauge, strain relief, firmware temperature limits, and thermal-runaway protection.
• 200mm footprint: not a drop-in for 235×235 beds unless your specific mod accounts for the smaller heater size and mounting.
• Retune after install: PID tune the bed and verify stable thermistor readings before printing unattended.
