Spring clamp terminal trays

I like these little spring clamp terminals. They measure 17 mm’s wide X 19.3 mm’s long. I found them on Ebay searching for spring clamp terminal. I think there are different dimensions for some of these but 17X19.3 are the ones that I have.
They are shaped like an H and have a through hole in the middle. They are kind of an odd ball size and don’t really fit into a din rail. I wanted to find a way to line them up so I made these little carrier trays. Use a tiny wood screw, #4 or 6? I don't remember. About 1/2" or 3/4" long.
I have 1, 2, 3, and 4 pocket carriers. I added adapter plates so I can mount these to a 35mm din rail.
Printed in ABS but these trays are only 3mm's tall so anything should work.
