Connect each of the 3 legs together by connecting the single point Strawbies with one of the half straws you cut earlier. (You will be left with a half straw that you won’t need.)
Attach a marker to your last straw with a rubber band, then place the straw through the center hole of the Strawbies structure.
Add a rubber band above the Strawbies structure to the straw holding the marker. This can be used to adjust the height of the marker so it comes in contact with the paper below.
Tape the leads of your pager motor to each side of a CR2032 battery. Since the motor will vibrate no matter how the power is connected, we don’t need to worry about the polarity of the battery.
What happens if you move the motor to other parts of the bot? How about adding more than one motor? Try attaching multiple pens to the legs of the structure instead of a center pen.
And hey! Find more projects in these downloadable Strawbees posters!
