Cat Wheel Wooden Running Exercise Treadmill Healthy Interactive Toy For Small And Large Cats w/Break Silent

I’m trying to put it together, however the installation plan is all wrong, got 4 types of screws on the plan, and in the bag. On the plan says 2 pointy ones 2 flat ones, in the bag 3 flat ones and only one pointy ..

Check the pictures.Is not shorty the price, unless you have a free weekend to figure out how to put all this together.
