This is my K'nex Charging Hub. My version of it can hold 16 phones, 2 tablets, and whatever other small things you need to be charged. It also has a table on top to hold any excess electronics. This design is very flexible and you can put a multitude of variations into it to make it fit your expectations. You can make it as tall as you want. There are three different types of "shelves" for the electronics plus there is an option to change the legs on the bottom of it to wheels so that it can roll around. Sorry that I haven't posted for another long while. Between moving into my new house and school, I've been busy. Enjoy building the instructable! Also, let me know if you like the format of my Instructables. Do they need to be simpler? Or are they too simple? Let me know, please! Thanks

Step 1: Base-Tabletop

This will be the same in every charging hub.

Step 2: Base-Layer

In pictures 14 through 15, I show you how to make a layer if it's the bottom layer and if you use the wheels instead of the legs.

Step 3: Attaching Table to Base

Here's how you attach the tabletop to the base.

Step 4: Legs

This is how to make the legs. You can do the legs and wheels together but I would not recommend it because it will be very wobbly.

Step 5: Wheels

This is how to make the wheel. Like I said before, you can do the legs and wheels together but I would not recommend it because it will be very wobbly.

Step 6: Phone Charging Shelf

Each of the coming-up shelves can be placed anywhere in the base. (Except for the tablet holder which we'll get to later). This is how to make the shelf for charging two phones.

Step 7: Tablet Charging Shelf

The tablet-holding shelf covers two layers. Therefore you cannot fit the tablet holder in one layer. This is what I mentioned earlier. This shelf holds one tablet.
