We have simulated and manufactured a shim coil array specifically designed to address fronto-temporal B0 inhomogeneities at 7T. The shim array is driven by an open-source amplifier, and facilitates slice-wise dynamic shimming. Complexity and costs are purposely kept low to allow manufacturing without prior expertise in electronics design and without access to extensive electronics manufacturing facilities.
