I am a revalidation ingeneer and I would like to find a light prothetic knee .
The normal "mass production" knees are around 370gram: this is to havy
The knee is for a little boy, 3 years old, his weight is around 12 kg.
A knee of 360 gram with al the other parts will make his leg more than 1 kg, somewhere around 10% of his weight!
I would like to have two parts printed in abs plastique, (the weight will be approximatif 70 gram for the plastique parts, there are some metal parts, 100 gramm, this makes the total weight 170 gram)
please contact me for sending the 3d files at
(I will pay for delivery and printing, I live in France, 56600 Lanester)
Thanks a lot!
