Getting PCGS boxes to close with NGC coins inside-HELP

I was told by another person on the forum that someone may 3d print something that allows the box to close/stay shut without using a rubber band. I have put a few search strings on ebay and come up empty. Does anyone here have suggestions on this? Where can I find such a product?

Yup a small riser collar on the box to raise the lid.

He printed me about 20 of them in a wide array of colors, they are excellent.
