Native Scale: 1/87 (HO Scale). The files are perfectly sized for HO scale dioramas but can be easily scaled up in your slicer (e.g., to 1/48 or 1/35) for larger, more prominent displays.

Printer Compatibility: Optimized for both high-detail Resin (SLA) printing and modern, precise FDM systems (such as the Bambu Lab A1 series). If printing in FDM/PLA at the native 1/87 scale, using a 0.2mm nozzle is highly recommended to capture the finer mechanical elements.

Supports: Required. Please ensure careful support placement around the chassis, wheel arches, and any overhanging cabin details to preserve the geometry.

Assembly: Designed to be print-friendly, with attention to structural tolerances so you can achieve clean prints and straightforward post-processing.

Leverage System: U can easily leverage the dumper with screwdiver. Copper phone line cable or fishing line 0.8 mm would be well fit for the leverage system.

As seen in the model renders: you can simply glue or tie one end of the cable or fishing line to the reel and the other end to the truck dump body.

For Bambulab A1 Combo all parts printed for 5 hours. using total 67 gr. filament.
