This stand is meant to work as a document camera for use as an assistive technology product or in an education setting. This stand combines with a smartphone and a tv box (like an apple tv or chromecast) to provide the functionality of a document camera without the expensive price tag.
Supports are required to help with the joint holes on the top of the stand as well as the rubber band slots on the legs.
UPDATE For those using a Makerbot Replicator, I have added a combined STL file that includes all the parts you need neatly arranged within the build platform of your printer!
Rubber bands need to be added to the legs and the top in order help stabilize the stand.
Rubber bands to hold the legs open and prevent slipping on the top.
Rubber bands on the legs to help them flip open and remain sturdy
Hooks on the bottom of the top piece allow you to attach any phone
Using it as a document camera
Once you have the stand printed and the rubber bands added you are ready to setup the document camera. Attach a smartphone to the top of the stand and secure with a rubber band. Then use the settings on your phone to mirror the screen image to a set-top box (like an Apple TV or Chromecast). Then open the Camera on your phone and you are all set. The stand was designed to hold the phone sturdy without the legs showing in the image. It is also tall enough to focus on a whole sheet of paper (at least with my iphone). With the price of the Chromecast around $35 and the Apple TV dropping to around $65 this stand can be a great addition to a smartphone allowing for visual impaired children and adults to magnify content without the cost of a large document camera.
I designed this stand in parts. I knew I wanted it to be small and collapsable. In order to get the legs to hinge, I used the Pin Connectors V2 designed by tbuser. I utilized the rubber bands to both assist in opening the legs as well as creating a non-slick surface on the top. When the legs are folded they rest against the center shaft to keep them from flipping out.
