#61 blue rubber bands on the Penny
I bought some smaller rubber bands that hold the boards together more tightly. #61 is a 2" by 1/4" band. I had previously used #64 bands which are 3.5" by 1/4".
The bands are much tighter and the board feels more solid. The blue looks better too. I am using plate mount switches with the 4x4 plates from the unquadquad.
I bought some M12 copper crush washers. 18mm outer diameter and 1.5mm thick. About the same diameter as a dime but the thickness of a penny. 17mm diameter washers may be too small to use with a plate as it might touch.
