I have this model I created for a little kid who has problems in their hands (muscular and/or skeletal). I was thinking that it would be awesome to release the design so anyone with this problems can 3d print it fairly cheap. I guess that the size of the model would be proportional to the size of the hand, but as you can imaging the hole for the pen will remain the same.
I am still prototyping the model and it´s not the final version, but I am already thinking about this part.
First picture, from left to right: v.1a @ 105%, v.1a @ 100%, v.2a @ 105%,v.2 @ 100%
Last picture is the newest version (v.2a, yellow ones were too big but sort of ok for my big hand to test and improve.
Thanks everybody in advance
