I DESIGNED IT FOR MY LASER K40 THAT CAME WITHOUT A FOOTREST, FOR 8 MM SCREWS WITH A HEXAGOMAL HEAD, ALTHOUGH THE HOLE IS 10 MM. I PREFERRED TO USE 8 SINCE WITH A WASHER I SOLVED THE PROBLEM OF THE SIZE DIFFERENCE.

IT HAS A HEIGHT OF 30 MM.

IN MY CASE I MADE THEM IN PLA AND THEN I GLUED PADS ON THE BOTTOM TO AVOID SCRATCHING THE TABLE.

I'VE ALSO ATTACHED THE EDITABLE FILE IN CASE ANYONE WANTS TO MODIFY IT TO THEIR LIKING. IT'S FROM FUSION 360.
