Anybody ever put a cartridge trap in a synthetic stock?

I was thinking how much I would like a cartridge trap in the stock of my Model 70 GP rifle. Anyone ever done or seen this?

Brockman does it, and it is a pretty slick setup, but cost a bit of coin.

I remember some company (Aussie?) that made a hinged side box that pivoted out so you could pluck ammo out of the top. These days with 3d printers, you might be able to do it on the cheap.
