I've made new super strong Wombot Z & Y motor mounts, including 3030 foot peg, to raise the Wombot up so these new bracket can be installed.
These brackets will raise everything up in the Z, but there room, so when installing turn the Z lead screw which move the whole motor, coupling, and lead screw up into the bottom of the 3030 bracket up top, do the same for other side.
Y bracket you reprint the "Z motor Right mount.stl", it a straight swap, then move the pulley to suit the belt.
So print 1 left & 2 right.
6 layers on all walls.
Add "support" to the square section only.
