Classroom Document Camera Stand

Just a note for people keen to give tips - what I really appreciate. Paypal.me is not available in New Zealand yet, so only direct Paypal transactions will work if you are very keen. Thank you again... enjoy. ==================================================================== My friend Susanne bumped into a problem: she has no classroom document projector for her classes, but it would make those sessions so much more visual and entertaining. It should be foldable, easy to carry and assemble... These devices are not common in NZ, and ordering one is quite expensive. I thought I'd give it a try and investigate what we could do. I found a pretty good app for mobile phones called DroidCam (the Paid version is DroidCamX, which comes with higher resolution). It works very well at capturing video feed and transferring it to the computer, which can be put on a projector. So then came the "easy" part: creating a foldable 3D printed Classroom Document camera stand to support any mobile phone - that's how I came up with this design. Features: - This stand is foldable to fit in a bag or even in your pocket. - The arm and device holder has perforations enabling 30,45,60,75,90 degrees arm inclinations so the height of the camera is adjustable. - It has different setup options: legs folded forward for example, for a 90-degree setup, or legs folded backward with counter weights like couple of books for example, 45 or 75 degree setups. - The change between setups can be done by pulling out the 40mm lock screw and adjusting the arm and device holder, then putting back the screw in the matching hole for the new position. Parts to print: 2x L1 2x L2 1x LA1 1x LA2U 1x Head 1x DeviceH You'll need these parts for assembly: 6 x M3 20mm 2 x M3 40mm 1 x M3 12mm (you might need to cut this one) M3 nuts, M3 flat washers and springy washers. When you put together L1 to L2 and L1 to Head, you might want to use one nut, one springy washer and another nut on top so it won't get loose so easily while using it... I used PLA printed on a Prusa i3 variant with 0.4 layer thickness and hot end. I created "_support" files to make it easier to print on regular printers, so I suggest you use those. I also rendered a folded and one scenario open model to help you understand how to build the thing together... Have fun!
