This is a computer dock, inspired by Griffin's Elevator Notebook Stand. I printed the eight parts in PLA and cut seven pieces of Delrin stock for the legs. Using Delrin was probably overkill - this will work with other (cheaper) materials.

When in the dock, the bottom of my 15" Macbook Pro is a little more than 3.5" off my desk.

1. Print (2) of each part. I used a stock Ultimaker at roughly 75mm/s and 10% fill. I didn't have to worry about supports.

2. Find 4' of 1/4" x 2" stock of something. Cut (4) legs 8" long, (2) leg 5.4" long, and (1) 5.2" long. The 8" legs are for the top and bottom and the 5.4" legs are for the back supports. The 5.2" leg goes across up front.

3. Find 14 bolts and respective tap, or another fastening method (glue? cable ties?). The holes in the printed parts are appropriately sized (and countersunk) for the hardware I used: 4-40 x 3/4" bolts through drilled and taped holes in the Delrin. I put each printed part in place on the stock to make drilling easy - 3/32" bit is fine if you're using 4-40s. Tap if you need to.

4. Assemble and use!
