Some folks have found it useful to reflect the webcam on a tablet/laptop down towards the keyboard, positioning a whiteboard or sketchbook or other flat object to project. Here’s a quick project for one:
It simply needs a small mirror, two SHCSs, and a matching coupler. It’s designed to be cut on a machine, but may need either a bit of cleanup w/ a file or chisel, or cutting in multiple orientations using suitable fixtures:
In order to make one, one need to know the thickness of the laptop lid/tablet — while tablets often include this in their specifications, laptops rarely have a separate thickness for the lid.
The spine of the mirror holder will need to be rounded at least enough to allow a reasonable positioning of the mirror.
There are several ways to accomplish such rounding:
use a cove radius endmill — unfortunately, Carbide Create doesn’t support such endmill geometry, so no 3D visualization, and not sure if a 4.5mm radius endmill is available. See: Design into 3D: Boxes: Magazine storage for some further information on this
The depth per pass is 0.508 mm for a #111 ball-nosed endmill — rounding down we want a stack of 0.5mm squares to indicate the depth we will be cutting to:
Mirror needs to be larger than 1"x1", so will have to see if some size is available in-between that and 3"x3" (the next size up at the local craft store).
