This is a tablet stand made to looked like welded chain links. The links and link assembly were modeled with Solidworks. Then the file was modified in Rhino to union all the parts. Then it was modified in Meshmixer to smooth the link joints, add the the little studs on the front three links and add support structure. This print is challenging - Lots of steep overhangs and bridging. I'll admit it took a few attempts to get it to print. Usually the bottom of link loops broke away from the support posts.
