I addded some extra height around the wire connections to hopefully enclose the bare wire. I have not wired mine up yet to test this, but should at least give it more cover.
I included the stl files & an openscad source file.
4 of Solderless_Roller_Motor_MountWithWireCoversNoEars_rev7_repaired.stl

The other stl file is used to combine with the exported file of the openscad file.
I was not able to combine these internally within the openscad file.
