Beer Bottle Lock

Firstly let me state that this isn't an original idea – recently a Beer Bottle Lock made the rounds on 3D printing news sites, originating from an Instructables tutorial by JON-A-TRON (see http://www.instructables.com/id/Beer-Bottle-Lock/ for the original). With Christmas just around the corner I wanted to design one for some fun with my family. Simply print out the two pieces and use any small travel lock to secure that final beer – whether it's yours or someone else's! This design differs from JON-A-TRON's in that no screw is required. The dimensions are fairly loose so it should fit securely on a wide range of bottle shapes; if you don't need this flexibility you might like to thicken one or two areas inside before printing. It could be snapped off, but this design is just for fun – if you're genuinely worried about people stealing beer maybe your friends are the problem. Follow how this was designed on my blog https://edditiveblog.wordpress.com/category/beer-bottle-lock/.
