More Shapes For The Unicorn3D Maker

Hello everyone, TCRcreations here.
I make Icons very very often and I am going to be making cursors very often soon when i get my new pc. I have been making loads of 3D Icons with the shapes avaliable on 3D unicorn. I was wondering if there where any extensions i could download for extra shapes or anything
Thanks guys!
Sincerely,
