I printed a couple hundred of these to give away from the #HIMSSmakers Makerspace at the 2019 HIMSS Global Conference & Exhibition in Orlando, Florida, February 11-15. I added a hole to each of the heels so the shoes can be ziptied to a purse, backpack, or perhaps a lapel. If printed large enough can be used as a smartphone or tablet stand.
If you print one at the conference, come on by for a selfie at the #HIMSSmakers Makerspace in booth 450! (Or just come by and get one!)
