Big box, small price
This box was the only big one I found at a sensible price ( Rapid chaper than others ). It is a beautiful 1960's style construction perfect for my use. Even just about works with Qmax hole cutters ( punch types ). M3.5 is same as UK mains socket long bolts for it's fixings (only 4 supplied with 6 holes ? ). I used these and M4 nuts to make cheap spacers to allow air flow. Cocktail sticks to locate the spacers. Strongly recomended
