The $29 Digital Picture Frame, from Amazon

Amazon regularly puts the Kindle Fire 7 tablet on sale for $29, a bargain for what you’re getting: a compact tablet with a fast, quad-core processor, 8 GB of built-in storage, expandable to 256 GB and, most importantly for this build, a 1,024 x 600 pixel display.

This tablet, combined with Amazon’s Prime Photos service and companion app, makes an excellent digital picture frame. Minus the frame, of course. That’s where 3D printing comes in, since printing a frame to house the tablet is easy. Here’s the finished product:

The model files for the picture frame are here on Thingiverse.com. I’ve uploaded both a single .STL (model) file to print the frame as one piece (requires a large format printer) or as four separate pieces, for smaller printers. For the sample shown, I had to print the frame as separate pieces, then super-glue them together. There’s also a separate model file for a small stand.

I use Amazon’s Prime Photos page to upload photos from my picture collection, and the companion app on my iPhone to automatically upload photos to Amazon’s cloud storage. Uploaded photos then appear in the Photos app on the tablet; choosing “slide show” starts a running presentation of random pictures. No other software is needed for this.

The end result: a $29 digital picture frame, courtesy of Amazon.
