RC Chassis Suspension and Steering CAD Collection - Thirty-Four STEP Files and 3MF

An original CAD collection containing thirty-four STEP files and one 3MF RC chassis project. Each STEP shape was opened and tessellated in FreeCAD for inspection, and every resulting preview plus all thirty-eight mesh resources in the 3MF was visually reviewed. The inspection meshes are not additional original deliverables.

The STEP set contains front and rear frame sections, left/right rails, a battery divider and stopper, upper and lower strengthening members, front and rear suspension-arm geometry, front arm and steering ball shapes, left/right front hubs and a rear hub, gearbox housing and top, a motor mount and support, rear gearbox axle support, a shock mount, rear spoiler, several steering arms and two servo-arm variants, steering balancer, left/right arm posts and steering posts, and an upgraded bumper. Two source files named Steering Arm and Steering-Arm contain different arm geometry and remain separately included.

All thirty-five original files are preserved unchanged and renamed in English. STEP provides CAD exchange geometry; the 3MF contains a grouped mesh project with overlapping components and repeated ball-like resources. It does not establish thirty-eight unique required parts or a verified assembly sequence. Confirm variants and print quantities before using both formats.

The source folder calls the project 100km_h. No vehicle speed, structural load, steering stability or operating performance has been independently verified, so this is not a 100 km/h performance claim. No wheel or tire mesh, internal gearbox gear set, exterior vehicle shell, real motor, servo, shocks/springs, battery, wiring, electronics, bearings or metal hardware was found in the reviewed geometry.

The cover depicts an illustrative empty-chassis arrangement. Actual dimensions, fits, bearing sizes, material requirements, print settings and tested assembly instructions remain unverified. MESHOPIA has not physically printed, assembled or driven this collection.

The new cover is a locally generated ComfyUI illustration based on the assembled chassis reference, with teal and ivory presentation finishes and a new workshop setting. Wheels, tires, rim faces, complete coil-spring shocks and electronics have been removed from the illustration. The small circular forms indicate empty hub/carrier positions, not supplied wheels or metal bearings. Appearance, inferred placements and surface finishes do not establish exact CAD shape, validated fit or speed performance.

Original geometry preserved and renamed in English; new illustrative assembled cover generated locally in ComfyUI.
