I work in Prosthetics and this is my first try using 3d priting. We scanned an ear and obtained some skin like elastic filament to print it in.
Even the softer filament is stiff when printed so I would like to thin the STL file. Ideally the base would just be a thin sheet (because it will stick on with glue) and then everything above that is thinner.
Ive tried a few tools but not got anywhere near to getting the ear thinned (so maybe its about 1-2mm thick and not 4-5mm thick.
Would anybody be able to try and thin it and advise me how they did it? I would be very grateful and it will eventually help people

I tried to upload the stl file and each time it never went in the list of uploaded files so I could not drag it to the bottom box to attach to this, what might I be doing wrong?
