3D model of a trapezoidal truss bridge for FFF 3D printing, PLA material, university academic coursework, ultra-light easy printing, one-piece molding no assembly, no support material needed. Strict 150mm clear span, two ends flat support (10mm width) for independent standing without external support. Exact midpoint has 10mm wide load hanger space, upper/lower chords at hanger position thickened to 3mm. Trapezoidal truss main body: upper/lower straight chords (diameter 2.5mm), web bars (diameter 1.8mm) with 75°/105° included angle to chords, trapezoidal unit upper side 15mm, lower side 20mm. No overhang, no closed cavity, smooth bar connection, minimal connection points for high printing accuracy. Total model weight (including adhesion layer) 7-8g (≤10g), STL format, adapted to Weedoo 3D printer (50mm/s speed, 220℃ temp, 0.1mm layer thickness), print time 1-1.5h (short printing time), uniform force distribution, good bending and deformation resistance.

$3D model of a high-performance simple supported triangular truss bridge for FFF 3D printing, PLA filament, University academic coursework design, ultra-light and high load-bearing, one-piece integral molding (no assembly allowed), no support material needed for printing (fits laboratory no-support printing parameters). Strictly comply with the 150mm clear span requirement, the two ends of the bridge are flat support structures, can stand independently stably without any external support, the support end width is 10mm to ensure stable placement on the table. A 10mm wide load hanger groove is reserved at the absolute midpoint of the bridge (the center of the 150mm span), the upper and lower chords at the hanger position are thickened to 3mm, and the surrounding truss units are encrypted to prevent local fracture under load. The triangular truss adopts an optimal 60° included angle design, the upper and lower straight chords are symmetrically arranged, the web bars are inclined at 60° to the chords, the chord di$
