I need a clean, printable 3D model of a 2019 Chevy Silverado 2500 HD body scaled to 1/12 for an RC truck. The file must open and slice trouble-free on my Bambu Lab P1S, so correct wall thicknesses, overhang angles and any necessary supports should already be considered. I’ll be printing in PLA and PETG. Please deliver the model in STL format; I also want an editable version I can tweak in Onshape later—STEP or direct Onshape file is perfect. I have no strong preference between a single-piece shell or a multipart design, as long as the final choice makes sense for print quality and ease of assembly on a 1/12 chassis. Key points to hit: • Accurate exterior proportions and body lines true to the 2019 Silverado 2500 HD 4 door short bed • Surfaces free of mesh errors so the P1S AMS and slicer don’t choke • Mounting areas left blank; I’ll add my own posts once I import the model into Onshape • File names and parts clearly labeled so I can identify doors, bed, cab, etc., if you decide to split it When it’s ready, just send the finished STL plus the editable file and a quick note on print orientation or any special settings you recommend for the P1S. That’s all I need to hit the ground printing.
