Well , it appears that this shape have been uploaded before , of course it is , I know that , I am the one who uploaded it , but yesterday I when I was uploading some of my products I found that I did not upload any 3d printing models since a long time , and so many of my products would be so cool in 3d printing .
So I decided today to upload them as 3d printable models this time , may be you can use them as gears or medals or even decoration , I do not know and I do not care , every thing I care about is my earning and the point remaining until the next level which decreased by uploading new models .
Do not do some fool reactions like What ?! you just do it for your own sake ?! , Of course I do , we all do , when you purchase any product you do this because you need and want it , not because you want to give the seller free money , then do not blame me that we are all selfish and racing for our sakes .
