Makin's Claycore contains three adapters in 3.5, 4 and 4.5 mm sizes for extruding hollow clay profiles. Combined with a suitable disc, each adapter creates an even tube around the core opening.

Hollow profiles are useful for beads, hinges, tubes, bails and lightweight structures. The three diameters let you match scale and wall thickness to the design.

Use soft, well-conditioned clay and check that the adapter and disc are seated correctly in the Ultimate Clay Extruder. Clean the narrow openings immediately after use.
