Custom Flexible Anatomical Heart Model (Helical Band / Unwrappable Design)

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+
