I can't say I'm thrilled with how Slic3r built the support under the badge. I snapped a razor trying to get it out. I decided to reprint and deepen the design to make it taller so the badge won't stick out so far from your chest. Once it was done, I took a dremel to the back to remove the extra ABS and then used a 3/16" bit in the drill press to drill an access hole for the single button on the BT device.
