Mechanical Design Finalisation — 3D-Printable Satellite Model (SolidWorks)

Overview We have a multi-part satellite design modelled in SolidWorks (7 parts: two hull halves, an internal deck, standoffs/bushings and secondary components, largest part ~120 × 137 mm). The concept and geometry are ~90% complete. We need an experienced mechanical designer to finalise the design for correct assembly and clean 3D printing, and to deliver production-ready files. Scope of Work Assembly integrity. Build (or rebuild) a proper SolidWorks assembly with all parts mated in a single coordinate frame. Run interference detection and resolve all collisions — the internal actuator components currently interpenetrate the hull by up to ~3 mm. Fix known defects (punch list provided): Remove a degenerate body inside the base part (0.04 mm-thick inverted sliver left over from a failed feature) and make each part a single clean solid. Correct a 2.0° rotational misalignment ("clocking") between the deck's four mounting feet and the base's four mounting bosses — the patterns are congruent but rotated, so the deck cannot seat. Add a fastening strategy: the base bosses are currently solid (no pilot/thread holes) and the two hull halves have no joining features at all. Propose and model screws/heat-set inserts/snap fits as appropriate (M3 preferred). Fix pin/bore tolerances: one bushing has 0.23 mm interference on its mating pin; another has 0.5 mm slop. Apply proper fits with FDM-appropriate clearances. Design for 3D printing (FDM, PLA/PETG). Enforce minimum wall thickness 1.0 mm (several regions are currently less than 0.7 mm), sensible hole compensation, print orientation and support considerations. Verification. Section views of all mating interfaces, interference-check report, and a simple assembly test print checklist. Deliverables Native SolidWorks files (parts + assembly), feature tree clean and editable STEP AP214/AP242 export of the full assembly Per-part STL exports in assembly coordinates Exploded view + basic assembly drawing (PDF) with fastener BOM Short change log describing what was modified and why What We Provide All current SLDPRT files and analysed STL exports A detailed defect report with measured dimensions for every issue above Fast feedback (same-day) via chat Requirements Strong SolidWorks proficiency (assemblies, mates, interference detection) Demonstrated DFM experience for FDM 3D printing — please share portfolio examples of printed multi-part assemblies English communication; questions welcome before starting Acceptance Criteria SolidWorks interference detection: zero collisions (excluding intentional fastener engagement) All parts single-body, watertight exports, no degenerate geometry Deck seats on bosses with all four fasteners engaging A test print of the assembly fits together without post-processing beyond support removal Timeline & Budget Target turnaround: 7–10 days including one revision round Please quote a fixed price for the full scope; milestone split acceptable (50% on assembly fix, 50% on final deliverables)
