Needed to print a separate holder for a couple of ICR18650s for an Ultrasonic Testing unit we have at work. We don't use it enough to keep the batteries conditioned. Seeing as the OEM thinks that a fair price for these batteries is about $450, I elected to buy a 4 pack from a local battery supplier for $60 instead... Moving them out of the unit so I can store them properly. http://www.thingiverse.com/thing:941081 Used S3D profile that @Alex9779 made. 2 Hours and 25 minutes E3D Everyday PLA from sample pack. .2mm Layer Height Temp: 205/60 The base seems to be slightly under extruded but it will serve it's purpose (first layer is fine though). Also sides are super smooth so I'm pretty happy with that.
