Product Description
This accessory was modeled in Tinkercad by Josh Burker and is licensed CC BY-SA 3.0. Edit or download it online at https://tinkercad.com/things/2SmRiO7mPlN. This optical viewfinder snaps into the USB port next to the front facing camera so that the laptop can be used as a camera when in tablet mode. Do not print this in metal! Upon receiving the first samples from Shapeways, the viewfinders did not fit well in the OLPC XO-4 laptop USB port adjacent to the camera. A 0.3mm x 12mm x 10mm shim was needed. I used a piece of flattened soda straw. This model has apparently printed fine on an entry level FDM printer (PrintrBot Simple). Shapeways uses SLS printers, which are more accurate causing the contraction in the model. The tab on this model should be thickened at least 0.3mm. I may do that and reupload. This model will insert fine into the XO-4 by applying some pieces of duct tape or glue on some other thin material to thicken the tab by the necessary 0.3mm.
