Here's a Dual Extrusion 40 mm High, 40 mm bore, Hex LED Candle Holder:To combine the files to extrude on a single extruder hold down the shif key and click Center & Arrange, this will merge the files.I used one of those cheap LED imitation flame candles, just to show effect :-)Could be heaps better with a straight out LED
Love 3D Printing, Enjoy designing, I like to print things that require no support.Dual Extrusion fascinates me to get it perfect.Hope you enjoy or can use our Things
