I’m building a physical prototype of a hospital-sanitizing robot and need a solid 3D model I can push straight to a printer. The core purpose is surface sanitization, so the design must clearly integrate both UV-light emitters and a disinfectant-spray system. The robot should be able to manoeuvre through a typical patient room or office and “see” everything you would expect inside—chairs, tables, desks, sinks and similar fixtures—so please include outward-facing sensors (LIDAR or depth cameras are fine) in the shell design to communicate that capability. Overall aesthetics can stay simple and functional; I’m more concerned with clear component placement and printability than flashy styling. Please make this very simple and easy looking. I don’t want it to look professionally done. I want it to look like an amateur did it but they took their time in doing so if that makes sense. Preferred workflow: you create a parametric CAD file (SolidWorks, Fusion 360, or comparable), export an STL set optimised for FDM printing, and supply a short assembly guide showing where the UV modules, nozzle array, battery bay and mainboard slide in. Dimensions should target a prototype about 30–35 cm tall, but keep wall thicknesses and tolerances reasonable for standard 0.4 mm nozzles. Deliverables: • Native CAD file with editable history • Print-ready STLs for all parts • Exploded view PDF or step-by-step images for assembly If you’ve modelled service robots or medical devices before, let me know—otherwise just show a quick portfolio sample so I can gauge style. I’m ready to get started as soon as I find the right fit.
