Need a document camera for teaching?
Have a webcam on your laptop?
Have, or have access to, a 3D printer?
Now you have a document camera for teaching!
Inspired by John Umekubo's pocket document camera, this holds a mirror to turn yourlaptop webcam into adocument camera for teaching. This is a from-scratch customizer design that will let you adjust the mirror angle to fit, including temporarily flipping the mirror out of the way to use the webcam as a webcam.
Choose the size that best matches the thickness of your laptop monitor lid. For example, if your lid is about 6mm thick, choose DocuCam-5-7.stl because 6 is between 5mm and 7mm. If you want to customize more, you can download DocuCam.scad and use the Customizer feature of OpenSCAD, or even modify the code and remix it into something new!
Not sure how thick your monitor lid is? Print the monitor lid gauge and slide it over your monitor. The number next to the smallest gap that fits is the best fit. For example, if that's the gap labeled "5", chose DocuCam-4-6.stl to print.
You can also print the mirror holder (DocuCam-Mirror.stl) separately from any of the clip sizes (DocuCam-Clip-4-6.stl and so forth). (The mirror holder is the same in each of the complete sets.)
The only downside is that the mirrors are sold in sets of 60, so you really need to make lots of these and give them away to all the teachers you know who are desperate for a document camera.
If you customize this to be the perfect size for a particular laptop, please remix with your customizer settings and publish your design, tagged with your laptop model, for others to use!
If you have suggested improvements to the design, I'll be pleased to look at merge requests at https://gitlab.com/mcdanlj/docucam

Notes:
I printed in PETG; most common filament materials should work. Resolution and infill don't matter much. The layer lines on the rounded features are intentionally used to hold the mirror position. If you use a more brittle plastic like PLA you will have to be more careful not to break the back off while installing it on your laptop, and measuring the thickness of your laptop screen will be more important.
Snap the two pieces together in the orientation they are printed. The arms may splay a little bit; this is intentional to provide friction to hold the mirror orientation in place.
The default 2" mirror size fits a set of 2" craft mirrors sold in sets of 60 at Amazon. Use double-sized tape, epoxy, or super glue to attach the mirror only to the center of the space. Don't fill the whole space with glue; you don't want to distort the image by making the mirror slightly curved. The mirror should fit inside the registration box.
