Ormerod 3D Printer - Upper z mount
The bear
This is an upgrade for the upper z mount
of the Ormerod printer. It stables the
z rod and reduces momentums, so
there are less unwanted forces reaching
out on the z movement. The x axis also
profits from it. It is printed with support
that you can cut out. IMPORTANT:
If your rod is not perfectly straight some
people recommend to leave the nuts off,
momentums are still reduced.
