Decorative K'NEX Toothbrush Holder With Rotating Display Stand

About: Hello everybody. I'm the Knex Inventor, and I love creating new concepts and designs with K'NEX. I will probably mainly post K'NEX instructables, but I may occasionally venture out and post something differe...

Here is my latest project: a decorative K'NEX toothbrush holder with a rotating display stand, powered by a Tethered Power Pack Motor. It can hold up to four toothbrushes, is very simple to make, and (in my opinion) looks very nice. It also includes a piece count. (see Step 1) I hope you enjoy making and using this! Below is a video of this project.

    Awesome! How fast does it spin?

    I would attach a drill chuck to it, and use it to help roast marshmallows :)

    Well, the motor that powers it spins at about 34 RPM, so that's about how fast the wheel spins. I should have a video uploaded soon, and then you can see for yourself.
