Compact mount for RC ESC with side base
A single-piece printable mount designed to organize the mounting of an electronic speed controller (ESC) in a radio-controlled car chassis. The geometry combines an elevated rectangular tray, with perimeter walls and an inclined interior transition, and a low side plate incorporating two circular mounting holes. The assembly measures approximately 62 × 59.1 × 11 mm and is delivered in a single STL. The original post, attributed to Marty, declares compatibility with a Traxxas Slash 4x4 HCG chassis and a Copperhead ESC. These designations are kept solely as nominal references of compatibility indicated by the author. There is no affiliation with their manufacturers, the mesh contains no logos or brand text, and the fit has not been physically verified in this file. Before printing the final version, compare the STL measurements with your chassis, the ESC, the screw pitch, and the available space for cables and ventilation. The official file was downloaded without reusing external photographs. It contains two closed and intersecting volumes within the same STL: the 11 mm high tray and the 3 mm side plate. Both bodies are watertight, have coherent orientation, and finite coordinates; no broken or degenerate faces appear. The intersection forms a set reproducible in the slicer and must be kept as a single print. For FDM, maintain the included flat orientation, with the plate and the bottom resting on the bed. A layer height of 0.20 mm and a 0.4 mm nozzle are a reasonable starting point. PETG may provide greater toughness and temperature tolerance than PLA, but the actual requirements depend on the vehicle's internal temperature, sun exposure, and vibrations. Check in the preview that the two volumes are sliced as a continuous set and that the perimeters around the holes are complete. Use three or four perimeters and several top and bottom layers to provide consistency to the tray and the areas near the screws. A moderate infill may suffice for a fit test; increase walls rather than relying solely on a high infill percentage. Supports should not be necessary in the original orientation, although the inclined transition should be checked according to the profile and extrusion width. Present the piece first without electronics and confirm that it does not rub against the transmission, steering, suspension, or bodywork. Mount the ESC without compressing its housing, leave room for the cables, and maintain the ventilation specified by the manufacturer. Use appropriate hardware and fastening for the actual chassis, without forcing the printed holes. After the first cycles, inspect for cracks, loosening, thermal deformation, and vibration wear. This design is not a certified structural part nor a protector against impacts, water, heat, or short circuits. The cover shows exclusively the verified printable geometry; it does not include the chassis, ESC, screws, cables, or other accessories. Any use in an RC vehicle requires independent validation of fit, material, ventilation, insulation, and fastening.
