Hi! Thanks for asking! The license under which this thing is offered (Creative Commons - Attribution - Share Alike) does indeed allow you to use the model in that manner. The only requirement is that you provide attribution (credit) to the model creator (me :), and that you offer your item with the same license. The way that is typically done is to provide a link back to the thing's page in your Etsy listing, which identifies the thing's creator and has a link to a very human-readable version of the license. Etsy listings that do not include attribution have been pulled in the past. Let me know if you have any other questions!
