Homebrew PCBs

Has anyone seen any kind of dual card edge mounting that would slide in lengthwise?

I brought fingers out to both sides of this card I made, it's 1.22" wide, and I'd like to be able to slide it in to a mounting.  Even using two card edge mountings that I can slide lengthsiwe into would work.  I'm about to get some polymorph to make one my self for proof of concept, but I'd rather buy something that would go into the second prototype.  I have 14 fingers on each side of the board, and the outside edge of the last finger is at 1.5"  This is also a double sided board, with logic on one side and power on the other.

For this first board (first etching ever) I'm going to solder on angled header pins to be able to plug wires on, but this is far from what I want it to look like when I'm done.
