LH Stinger Carbon Fiber Bed Kit (Bed + Carriage Plates)

The complete carbon fiber bed stack for the 200 mm LH Stinger: the bed plate plus both carriage plates. All three are cut from 3 mm matte 3K plain-weave Toray carbon fiber to the official LH Stinger DXFs — the same parts our Starter Kit ships with, sold on their own for a scratch build, a re-bed or a spare.

What's in the box

• 1× bed plate — 200 × 200 × 3 mm with four countersunk mounting holes, cut to CF_Bed_200mm2_x3mm. This is the surface you print on.
• 2× carriage plates — 3 mm, cut to CF_Carriage_Plates. The round spacers and the two cable strain-relief arms are still attached on breakaway tabs: cut them free and keep them, the assembly uses all of them.

How it goes together

• Carriage: the two plates are epoxied into one dual-plate carriage — the project's picks are Loctite Power Epoxy Universal (150 °C) or J-B Weld High Heat. Cut the tabs flush and file the belt holes smooth first so the belt never rides a sharp edge. FYSETC's Rev 2 kit ships this step done; ours ships the raw plates. Steps: CF Carriage Assembly.
• Heater: the polyimide heater bonds to the underside of the bed plate on its own 3M adhesive, positioned with the project's alignment jig; let the adhesive cure before the first heat-up. The matching heater is our LH Stinger 24V 200mm Polyimide Heater (not included here).
• Print surface: the Stinger prints straight on the carbon — bare, or with a wipe of glue stick for filaments that need it. A PEI film is optional; the 192 mm cut of our 20mil Ultem PEI sheet fits this plate. Adhesive film is a commitment: the adhesive is very hard to get off again without marking the carbon, so the project's advice is to start bare and only apply a film once the bed is finished and no longer coming apart.

Specifications

• Printer/project: LH Stinger open-source Cartesian FDM printer, 200 mm high-speed bed configuration
• Bed plate: 200 × 200 mm nominal, 3 mm thick, four countersunk mounting holes
• Carriage plates: two 3 mm plates to the official DXF, spacers and strain-relief arms on breakaway tabs, epoxied together by the builder
• Material: Toray 3K plain-weave carbon fiber composite, fine matte finish on both sides
• Print surface: bare carbon (project default); Kapton or PEI film optional
• Not included: heater, epoxy, fasteners, thermistor

Fitment

• For the 200 mm LH Stinger bed setup, not the larger 235 × 235 mm bed option.
• The LH Stinger Starter Kit already includes this bed, carriage and heater; this listing is for building from the BOM, re-bedding or keeping a spare.
• Build documentation: the official LH Stinger GitHub and its Bed Heater wiki page.

Gotchas

• No magnet, no spring steel: the Stinger bed stack has neither — the carbon plate is the build surface.
• Carbon fiber conducts electricity: keep the heater leads and solder joints insulated from the plate and check for continuity between the heater wires and the carbon before you power it.
• Bed temperature: the project limit for the heater on this bed is 110 °C.
• Carbon dust: cutting the tabs, filing, drilling or sanding carbon fiber calls for ventilation, a respirator and wet methods.
