I am willing to give you some help.
If I make a version 2 I will release all of the version 1 (right now I am just updating some of my quickly designed parts). This is just to help keep bad designs from thingiverse. There are a ton of remixes that are great, but If someone had the cad files they could easily inadvertently change a dimension and make the whole thing not work right. I have released enough bad parts myself. I wouldn’t want to lose anyone to someones mistakes.
I would double check with the grant, my professor would have never let me rebuild a previous product without significant differences.
If you do release files please follow the license I have used on thingiverse.
