sortainer- alternative brand insert boxes to fit?

[gruz]

I'm looking to add a bunch of insert boxes to my sortainers.  at $15 for 4 medium ones, this could cost $135 for one sortainer (I have a few that I'm hoping to outfit). 
does anyone know of other brand boxes that will fit decently in the sortainer drawers? 
almost $4 per box seems crazy given what it is. 
This is a mobile set up so there's a fair amount of movement, meaning a snug fit is preferred to prevent a mess upon opening the drawer...
thanks in advance

If you have a 3D printer, or a friend with one, you could possible 3D print what you are looking for.

You can try these folks. They have lots of sizes, one inch, 2 inch, 3 inch high

Prices are very reasonable.
