Worried about the news reports that "sitting is the new smoking"? Are you sitting now? Stand up at your desk and tone your backside while you work with this handy completely adjustable laptop stand. The open-source stand is made from 3-D printable joints and open-beam. Press on the spring loaded button in each joint to change the angle - it can adjust from flat for storage to "tv-tray" height or anywhere in between. This is but one of many useful products our group, Michigan Tech's Open Sustainability Technology Research Group has found can save consumers money by fabricating it themselves with the use of a 3-D printer. For more information see our economic analysis hereButton preparation Top cover preparation This version of the stand was developed and prototyped by Michael "Buck" Poszywak. It uses OpenBeam which is really handy for prototyping things but both a little expensive and a bit less rigid than we would like for this application. We included the OpenSCAD file so you can adjust the hinge parts that attach to the OpenBeam so you can fabricate similar laptop stands with thicker Al extrusions, wood, etc. To out compete even the highest-end laptop stands you could also put fancy art work on the sheet with a laser cutter or cut in vent holes and mount USB powered fans. You can also add a lip or holder for being able to use the stand at weird angles e.g. upside down in bed. The open-source laptop stand can also be used as an art table for both the young and old. The joints can be used for any application where you need an adjustable but long-term fixed position. So for example in the office you can use it as a document holder or bed as a book holder...and on and on.
