Small parametric box w/ primer tray insert

A small parametric storage box with an insert for 209 type primers often used in Airsoft Grenades and other noise making devices.

The box can be resized and used for any purpose, the default sizes given are for an insert that exactly fits the default box tray and holds 10 209 W type primer caps. 

I made this is response to my Airsoft Grenade System as the off the shelf Fiocchi packaging had a tendency to slide open and dump all it's contents in my range bag, this sliding case system allows me to safely carry smaller quantities.

If the tray is too loose or too tight in its outer case try adjusting the tolerance value and reprinting the outer case.

 Updates 

Updated the parametric model of the primer tray to include an interlaced option, so that only one primer at a time would be released when you slide open the tray. Included an example stl of that design also.
