This is a timer used for timed shooting competition such as benchrest or ARA shooting where competitors have a limited amount of time to place all scoring shots.  This uses a large display kitchen LCD timer available through Amazon. (current link below)

The benefit of this design is that it allows the ammo block to be changed for different shooting events where different calibers are being used.  If you need a special block feel free to contact me and I will add it to the collection.

The mounting blocks for the timer are specific to the contour of this clock.  If you intend to use a different clock you will have to design a mounting block.

All parts have been designed to be printed without supports.  Just make sure any countersunk feature is pointing up in the “Z” direction

4 pcs M4x 0.7 nuts

If you are shooting 22LR and use Lapua/SK or CCI I have included an ammo box that lifts every other row of ammo and uses the manufactures plastic frame so ammo does not need to be transferred to a new box.

If you do not have an AMS, which I do not, and would like to get the lettering at the top of the ammo tray in a contrasting color, pause the print 4 layer above the top of the sliced model.  This allows you to change to a different filament and finish the print.  I found this to be well worth the effort to have some nice contrasting lettering.  The left side panel and the ammo blocks have some lettering and looks good in a contrasting color.

Also if you use this for more than one discipline and print a second block it can be stored in the base so you keep all your parts together.  More than that you are on your own for storage solutions.
