3D Modelling of 1:87 Scale Railway Structures (Fusion 360/CAD)

ProtoDutch is seeking a skilled 3D modeller experienced in Fusion 360/CAD to create 3D-printable scale models (1:87, H0) of historic Dutch railway structures. We start with a small paid trial: one pier panel with visible stones and recessed joints. Deliverables include STEP and STL files (F3D is welcome but not required).

The four structures (1. elevated railway piers, 2. brick viaduct, 3. arch bridge, 4. swing bridge) can be awarded separately. Please provide a fixed price and delivery date per structure, along with a separate price for the small paid trial pier panel. Exclusivity is required: all models are made solely for ProtoDutch and may not be shared, sold, or published.

Requirements:
- Deadline: All models delivered by 15 November 2026.
- Print specifications: Each part max 300 x 300 mm, minimum wall/detail thickness 0.4 mm, printable on FDM (0.4 mm nozzle) and resin. Structures are split into a kit of flat-printable open panels with separate cover parts. All piers are printed in resin with visible stones and deep recessed joints.
- Input: ProtoDutch will supply drawings and photos; the drawings are leading for all dimensions.
- Detail level: Medium (profiles, mouldings, recessed joints), exterior only.
- IP: All rights transfer to ProtoDutch upon payment.

If the collaboration works well, ProtoDutch is looking for a long-term partner for ongoing modelling work.
