RangeTech Timer Gun Mount

I purchased a RangeTech shot timer to practice getting my times down for Steel Target, Defensive Pistol and for Timer for practicing for my NRL22 matches. After getting it found that most all shot timers have issues picking up 22lr shots. One suggestion was to get the timer closer to the muzzle. Since I got out to practice by myself and NRL is positional and you are not always in one spot I figured why not see about mounting the timer on the gun. So one Arca Quick mount and a Piece of 1"x1/8" thick Alum bar with a bit of tape I went to range and did a bit of testing. Sure enough with the timer mounted it was picking up every shot. So I decided to Refine my mount from Duct Tap and coroplast to 3d Printed model mount. So this is what I cam up with.
