The idea - Collect human nail clippings to ground up and use to print a 20KG, real size Rhinohorn.
The reason - Rhino conservation
The thinking behind it - I heard that Rhinohorn consists of exactly the same type of material (keratin) as human nails. If we can collect enough clipped nails, clean it (eeuw), grind it up to a paste/resin and use it in a 3D printer to print a full sized Rhinohorn. Would be interesting to speak to buyers of Rhinohorn in the Far East to have their perception.
Progress - 1% (Put thought "on paper").
1. Can it be done? Need to hear from experts.
2. Collection (points) and shipping. Storage.
4. Grinding it up.
5. Make a paste/resin.
6. Acquire/borrow/commision the right 3D printer to do it on.
