I ran across Nervous Systems [email protected]/* <![CDATA[ */!function(t,e,r,n,c,a,p){try{t=document.currentScript||function(){for(t=document.getElementsByTagName('script'),e=t.length;e--;)if(t[e].getAttribute('data-cfhash'))return t[e]}();if(t&&(c=t.previousSibling)){p=t.parentNode;if(a=c.getAttribute('data-cfemail')){for(e='',r='0x'+a.substr(0,2)|0,n=2;a.length-n;n+=2)e+='%'+('0'+('0x'+a.substr(n,2)^r).toString(16)).slice(-2);p.replaceChild(document.createTextNode(decodeURIComponent(e)),c)}p.removeChild(t)}}catch(u){}}()/* ]]> */ app, based on their Kinematics post. This is a bracelet I made for my wife based on that system. Can't believe how well it turned out! You can download and print this thing, or go to the above link and make your own.After I designed the bracelet and downloaded the stl, the first print failed: Turns out the stl was pretty messy (many holes and separate shells). I ran it through Netfabb Cloud and the resultant stl (uploaded here) printed great on my Replicator (1). I got ahold of Nervous Systems: They said they're still working on the app, and hope to have those issues resolved in the future.
