Project title: Custom Flexible Anatomical Heart Model (Helical Band / Unwrappable Design) Description: I am looking for a 3D designer or engineer to create a custom anatomical heart model based on the helical myocardial band concept (Torrent-Guasp model). The goal is to design a heart that: Can be physically unwrapped into a continuous band Mimics the spiral muscle structure of the ventricles Is suitable for flexible fabrication (silicone or TPU 3D print) Requirements: Create a continuous helical band geometry Ensure the model: can be twisted and stretched without breaking can be reassembled into a heart shape Deliverables: STL / STEP files (OPENSCAD files, it free software if you dont own it already) Optional: segmented version for easier fabrication Nice to have: Experience with: anatomical modeling flexible materials parametric CAD (Fusion 360, SolidWorks) Reference: Based on “helical heart / myocardial band” dissections (YouTube references will be provided) “This is not a standard anatomical model — it must behave like a continuous strip that can unwrap.” Expected cost ranges CAD design: €50 – €300 (simple) / €300–€800 (advanced, realistic) Silicone fabrication: €100 – €500+
