  Magnetic Weyl semimetals exhibit intriguing transport phenomena due to their
non-trivial band structure. Recent experiments in bulk crystals of the
shandite-type Co$_3$Sn$_2$S$_2$ have shown that this material system is a
magnetic Weyl semimetal. To access the length scales relevant for chiral
transport, it is mandatory to fabricate microstructures of this fascinating
compound. We therefore have cut micro-ribbons (typical size
$0.3~\times~3~\times~50$\mu$m^3$) from Co$_3$Sn$_2$S$_2$ single crystals using
a focused beam of Ga$^{2+}$-ions and investigated the impact of the sample
dimensions and possible surface doping on the magnetotransport properties. The
large intrinsic anomalous Hall effect observed in the micro ribbons is
quantitatively consistent with the one in bulk samples. Our results show that
focused ion beam cutting can be used for nano-patterning single crystalline
Co$_3$Sn$_2$S$_2$, enabling future transport experiments in complex
microstructures of this Weyl semimetal.
