11. A cooling bit holder storage system, comprising:
a first compartment longitudinally extending along a first axis, the first compartment comprising:
a first opening;
a first end located opposite the first opening along the first axis; and
a first material having a first melting temperature;
a second compartment longitudinally extending along a second axis parallel to the first axis, the second compartment comprising:
a second opening;
a second end opposite the second opening on the second axis; and
a second material having a second melting temperature;
a plurality of connectors that couple the first compartment to the second compartment, the plurality of connectors extending along a plurality of planes between the first compartment and the second compartment, such that each connector of the plurality of connectors contacts both the first compartment and the second compartment;
a cover plate coupled to both the first end and the second end, the cover plate comprising a third material having a third melting temperature that is higher than the first and second melting temperatures; and
an insert coupled to the cover plate, the insert extending into the first compartment and the second compartment, the insert comprising a fourth material having a higher melting temperature than the first and second melting temperatures.
