I found my design which I shared for free at GrabCAD grabcad.com/library/injured-heart appeared for sale at Kraftwurx. Ironically 3D printed models of my design Injured Heart are being sold by a user called Admin.

Leaving aside legal aspects I was wondering how ethical it is.

Hello,

The staff at Kraftwurx.com does respect all intellectual property and designs. We have removed the published product in question. It seems your model being available free online somehow came into our possession without any of the proper information or credit to the creator associated with it. We apologize for the confusion. I checked the product to see if any sales of the item had been made and none were found. Please rest assure we did not intend to disrupt or upset your endeavors. We think it is an attractive model and encourage you to participate in Kraftwurx and possibly make this and other 3d models of yours available for sale as real 3d printed items on Kraftwurx.com.

Again we apologize for the confusion.
