RC Fire Truck Box Design 1/14
Budget: €30 – €250 EUR
Project Description: I am looking for an industrial or mechanical designer with experience in CAD software (SolidWorks, Fusion 360, or similar) for the complete design of the rear fire engine/extinguishing body of a 1:14 scale radio-controlled (RC) fire truck.
I already have a fully functional modular metal chassis and a metal cab from a MAN TGS truck. The sole objective of this project is to design the rear bodywork using a real fire truck (Iturri body on a MAN chassis, registration 5178 NGP) as an exact reference, adapting it precisely to the RC model chassis.
The project requires a hybrid manufacturing approach:
Structure and Exterior Paneling (Laser Cutting): The main cubic frame, side walls, rear fenders, and roof must be designed using thin, foldable/interlocking sheets (aluminum or thin-gauge steel) prepared for industrial laser cutting.
Aesthetic Details and Accessories (3D Printing): The embossed slats of the side/rear tool blinds, light trim, simulated hinges, access ladders, and details of the collector/water inlets in the rear pumping area will be modeled for high-resolution 3D printing (Resin/SLA).
⚙️ Mandatory Technical Requirements:
RC Chassis Adaptation: The design must incorporate mechanical supports and anchor points for attachment to the metal chassis rails using standard screws (M2 or M2.5), without interfering with the rear leaf springs or the driveshaft.
Electronic Integration and Cable Routing: The rear box must be completely hollow or have a removable double bottom to house and conceal the main electronics (batteries, Servonaut G24 ESC, sound modules). Specific pass-through holes and cable channels must be designed to route the cables to the lights.
Functional LED Lighting System: The model must include the exact housings and perforations for installing 3mm diameter LED optics or SMD micro-LED panels (rear light clusters in the bumper, blue priority strobe lights on the roof and upper sides).
Scale Fidelity: Respect the layout of the real model (two double louvers per side and one rear louver) with the curved, dual-axle wheel arches.
Required Deliverables:
The selected freelancer must deliver the following technical documentation:
Laser Cutting Plans: Vector files in .DXF or .DWG format, perfectly organized by layers (cut lines, mark/fold lines).
3D Printing Models: Solid .STL or .OBJ files (manifold), optimized and ready for resin slicers (Chitubox/Lychee type).
Complete Assembly File: The editable native model or a universal exchange format (.STEP) containing the entire assembled unit for verifying general tolerances before manufacturing.
Basic Assembly Guide: A simple exploded view diagram showing how the laser-cut sheets fit together and where the 3D-printed accessories are screwed in.
