80Pcs Hammer Head T-Slot Drop-in Stud Sliding Bolt Screw Nut Assortment Kit, for European Standard Aluminum Profile (M5-20 Series)

I still havent actually made the changes yet but while overall I liked the hinges, because of how they mount I cant put several sets of cubes side by side and have them lock together.

This will eliminate the hinges and latch and let me link a whole bunch of them together side by side
