Pi Box Version 3 -

thingiverse

This is a smaller version of the Pi Box, perfect for users who want to print it without needing an overly large print bed. Many people were interested in the original Pi Box, but its size was a major obstacle. Here's a scaled-down model that fits perfectly with the Raspberry Pi B+, along with some creative variations to keep things interesting. Besides your Raspberry Pi B+, you'll need a few more items: an external USB hard drive, one SD card (minimum 4GB class 4), a short panel-mounted HDMI cable (#978), a short panel-mounted LAN cable (#909), and a short panel-mounted USB Cable (#908). You'll also require a micro-USB male-to-female extension cable and a 16mm switch (#917). The part numbers above in parentheses are from www.adafruit.com, used here as examples. You can easily find cheaper alternatives on Amazon or Ebay. A word of caution: I haven't personally printed this design, but it's specifically designed for users who loved the original Pi Box but were unable to print it due to size constraints. Any feedback or concerns would be greatly appreciated. Instructions: 1. Print the base. 2. Print one divider piece and one grill. 3. You can also choose to print either an expansion top or a cover (or both), perfect for projects requiring extra space. The idea is to use it to house a USB hub and a small fan, among other things. Now that you've printed all the parts, let's assemble them together! Mount your Raspberry Pi B+ along with its panel-mounted cables. Next, we'll be combining the micro-USB extension cable and power switch, so that you can turn your Raspberry Pi on and off using the front button. This will involve attaching the female end of the cable to a rectangular opening at the back of the box and soldering one of the cut wires (preferably the positive one) to the switch terminals. Mount your external hard disk onto the divider piece using double-sided foam tape, which makes mounting much easier and also provides the HDD with some shock protection. Then, simply position the grill and top cover. In keeping with this design's minimalistic theme, I've chosen not to use any screws (other than double-sided foam tape) for assembly purposes, mainly because 3D printed screw threads can be quite inconsistent. With that, you should have a complete Pi Box mini case ready to house your Raspberry Pi B+! Enjoy using it.
