(this refers to the PDF document you can purchase online)
On the page the URL link printed is "thingiverse.com/hairygael"
BUT, the actual embedded URL if you click will take you to "thingverse.com/hairygel"
and this triggers a virus/malware warning Trojan:JS/IFrameRef - Severe.



Unsure of actual actions taken since this is automatically removed by my virus software, but buyer BEWARE !!!
If you manually type the correct thingiverse URL as typed on the page, it does indeed take you to the correct page.
I checked all other links in the document and this appears to be the only one that has been tampered with.
Makes me wonder how/who at Make magazine changed this URL. Obviously someone with a deep internal knowledge of the document and its creation.
I've emailed MAKE magazine and gotten a response back of "thanks.. we'll look into" but have not heard anything else since.
