thanks bart!
the feet made from a rubber band, cut up and attached to each leg to improve traction. now it walks fine, even on glass
that was the quickest solution I can think of at the time.
the new elasto plastic material might be a suitable material for 3d printed versions of those feets, if it's rubbery enough...
will know soon, have an elasto print order due to arrive sometime next week.
