We demonstrate a surface-electrode ion trap fabricated using techniques transferred from the manufacture of photonic crystal fibres (PCFs). A pre-step to a drawn out PCF is a cane that has the same regular hole pattern at a larger (100 micron) size. Filling the holes with gold wires and using them as electrodes provides a relatively straightforward route for realizing traps with electrode structure on the 100 micron scale with high optical access. This makes it useful for interaction with strongly focused laser beams and cavity integration. The fabrication method should allow building traps of similar geometry at sizes on the 10 - 100 microns range that might allow trapping at the tip of an optically guiding PCF, and provide a route towards small two dimensional arrays of ion traps.
