Capture a movie on your phone of the object by walking around it. If possible shoot it from different angles e.g. from above looking down, below looking up, side on etc. When you film it, walk around it or move the camera around it in a full 360 revolution (or even a couple of revolutions). You should get something like this (note that the image below is a resized copy of the orignal downrated to 1 fps):
Put the video into an empty folder and then use ffmpeg to extract the frames. You can experiment with different frame rates but generally there will be little value in extracting at 60fps or whatever your phone natively shoots at.

Every so often, you may find yourself needing to preserve a website in its current state. Whether this is in advance of a significant website change, general documentation, or the possibility that the site needs to be taken offline, it is a good idea to archive the site so that it is navigable locally and without the need for a server.
Introducing HTTrack HTTrack Website Copier will do just that, download a website to a local directory, build all the directories, get HTML, images, and other files from the server to your computer.
HTTrack has a GUI for Windows that works really well: http://www.httrack.com . You can also use this tool from the command line. See the following steps to archive websites using the HTTrack command line tools.
MacOS Installation: First, you will need to install HTTrack locally. On macOS, https://brew.sh/ is the package manager of choice (as opposed to MacPorts). Homebrew is simpler to set up but does require you
