  We present a magnetic field confining coil with a sub-$10^{-3}$ field
uniformity over a large fraction of the coil. The structure is entirely made
out of printed circuit boards (PCBs). The PCB design allows to tailor the path
of wires to fit the required geometry. We measure the field uniformity with
cesium magnetometers in a field range from 1 to 10 $\mu\mathrm{T}$. Our
application uses such a coil for an atomic magnetometry-based current
controller.
