This curler was virtually new when it was dropped and the tip shattered. The two-part replacement tip was printed in ABS on a Makerbot Replicator. The print finish wasn't perfect, but three years on and it is still in service, despite many subsequent drops.
There seem to be several variations of this curler on the market in Australia. This fits the 19mm barrel VS Sassoon Studio Tools Instant Heat Ceramic Curler.
