Prompt
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.
