They were hard to lock together, so I made a small change to the lock chamfer.

This is an update to my original Dash-Board. I recently purchased more Dash Buttons than I had room for on my Dash-Board, so I designed one that I can expand.

I still have 10mm round magnet pockets on the back, you glue them in and they attach to your refrigerator on the edge of the magnet.

There is also a Left and Right end cap. They clip together very tight, so I might tweak the design a little, but they lock together really good.
