When AMG released the worlds smallest (read, cutest) shot timer, they forgot to release something that'd make it easier to keep with you! Sure, that lanyard that comes with the timer is handy to have around. But if I'm gonna have the Tamagotchi of shot timers, I need to have it where I can easily see it! 

No more fishing it out of your pocket! No more wearing it around your neck! It's as easy as slipping it right over your outer belt. 

What's more? Now you can keep the timer in a little protective case (that doesn't impede the timer's ability to pick up sound) that slides into the belt keeper via the integrated tracks. 

This idea isn't novel; I think I've seen a shot timer that has a hinged belt keeper so you can glance down and check your split times. But what is nice is that I added two magnets so that it doesn't flop around on you while you move from position to position. 

Assembly Notes:

The magnet fit is close to a press fit for both; p1 prints at a 45 with no supports via the designed support (just break the tabs off when it's done) and P2 prints on it's side. I recommend using a 5mm brim to ensure that it doesn't curl off the bed, hinge parts 1 and 2.
