Nexus Charging Station

thingiverse

I work at a school, where we have fifty Nexus 7 tablets to charge. To make this easy, I created a charger for ten at a time. The stands hold a Nexus 7 in a gel case perfectly. Inside the box is a ten-port powered USB hub with its power supply unit. I bought a 10-port USB hub from Amazon that uses a four-amp power supply unit. If left overnight, it charges all ten Nexus devices to 100% fully charged. However, I still recommend using a power supply with a higher amp rating. You'll need to get ten short micro-USB to USB cables to prevent cluttering up the workspace. To make this case, I cut out the top and bottom parts from three-millimeter acrylic sheets on a laser cutter because I've always had trouble printing flat objects on our Makerbot 2X. The .DXF files for these parts are included in the design. While the slots for each cable aren't entirely accurate, everything fits together perfectly well enough to look good. There's a hole for a two-core cable going straight to the power supply unit. Throughout this case, four-millimeter nuts and screws are used securely. The case is completed with four rubber feet to keep it stable and steady.
