Case for my plantronics voyager edge bluetooth headset. Dont want it to get crushed in my bag. Snaps in solid for me, but you may need to adjust fit, my printe under-size inner diamete by 0.2-0.3mm more than most. The far end pokes out just enough it shouldn't get pushed by accident, but it allows you to remove easily. Will add pictures when I can. I've provided STEP and SLDPRT in case you want to edit.
