Here is a very funny element to put in your Knex ballmachine. It works about 99% and is nice to look at. The knex ball goes in his head and the face becomes angry. After a second he becomes like he was and lets the ball go true his mouth. If there is a problem, let me know in the comments.
Step 1: Lets Begin.
Step 5: WARNING.very Important Step.
Put the eyebrows down and look that the 3 gray conectors in the head are exactly in this derection!!! You can modify it with the yello and red gears.
Step 6: Another Important Step.
Make sure that there is alittle bit of space on every moving piece!!!
If the eyebrows are down wen the mouth is closed, It's correct.
Step 8: Another Important Step.
Slide the white rode completely to the left.
Step 9: The Final Steps.
Awesome! now hold the head by the bottom and try it out!!
poil87 made it!
