30mm knob-nut for M6 bolts to make enclosure from styrofoam.

This is special handle for M6 bolts with D=30mm.

It is usefull if you want to screw togather two pieces of styrofoam.

Wide nut wont sink inside styrofoam  - it has nice feel and it can be used with long bolts.

Tested on styrofoam 30mm (builded enclosure from styrofoam ):

• long hex nut must be glued with sanitary silicone inside styrofoam,
•  all wals are tightened by M6x65mm (depends how dip you glue nuts),

This is easy solution for styrofoam enclosure for 3D printer.

Styrofoam ( I mean XPS) will keep right temperature inside enclosure for better prints.

Happy printing
