I picked up a cheap endoscope on Amazon (it's this one if you want to compare against one you may have https://a.co/d/ehPcz4h) and it works well but once it's out of the box it was really hard to wrap up and put away nicely. I create a quick holder for it. the center has two slots where you can insert the USB plug, then wrap the rest of the scope around it.
It's simple and it works.
