This is a knee-sy step.

If you aren't into printed parts, you can use a dowel instead. Actually... that might be faster!

Apply hot-glue to the end of the leg.

(the notch in the leg is an allowance for a screw... which will make sense in a bit)

I turn the leg slightly here to prevent flexing in the legs as the body moves forward / backward.

Twice as nice.

No screws?

Nope... we'll be adding electronics to the inside later and don't want anything inside the body that might cause shorts, sparks, or magic smoke to escape.

Time for toes.
