LH Stinger 24v 200mm Polyimide Heater
Couldn't load pickup availability
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

- Official design reference: 2.66Ω at 25°C, 216W at 25°C (±10%), 1oz copper

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.

Shipping:
US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.
International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.
I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or rerturned, I will not be responsible for rerturning your shipping cost.
If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.
Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
