Original idea for lampshade: http://www.thingiverse.com/thing:19478 I have made lamp base with screw thread, hole for cable... and holes for bulb holder (G9 bulb holder recommended). I also made hole and screw thread in lampshade for easier connection. Max. bulb diameter is 25mm (0.98 inch) and height 68mm (2.67inch).If you like my free designs consider supporting me by: Buying something at my international shop: http://en.dawanda.com/shop/Protonik Buying one of my premium designs: https://pinshape.com/collection/65209-protonik-premium-designs Buying something at my Shapeways shop: https://www.shapeways.com/shops/binfinite Or paypal donation: https://www.paypal.com/webapps/mpp/send-money-online [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){}}()/* ]]> */You can also check out my: Homepage: https://www.protonik.pl Facebook profile: https://www.facebook.com/protonikpl?fref=ts YouTube channel: https://www.youtube.com/channel/UCMBmK0HJZu80GwODaSXFytg
