How to Construct a Tomato Paste Robot Head
A quick how to build a toy robot head out of a tomato paste can.
Materials: tomato paste can, bolt, end cap nuts, caster
Take caster apart
The part you need
Cut off end of bolt with hacksaw
Make sure end caps fit
I made two 1/4″ diam holes in the can using a metal punch (basically a hole punch for metal), you can also use a drill. Holes are roughly 3/4″ from the bottom and spaced 1 3/4″ from each other.
Put it all together. Attach one end cap and thread bolt through one hole in the can. Place caster piece inside of can, thread bolt through both holes in caster piece. Thread bolt through other hole in can. Attach other end cap to other end of bolt.
You can draw on eyes, cut holes, or add lights. Anything goes. You now have a swiveling, nodding tomato paste robot head.
