This Tentacle System kit includes a baseplate that fits inside an Altoids box along with parts needed to create a camera or webcam stand.
In addition to the base, there is a 75mm straight extension and a ¼" threaded grip to hold a light camera or webcam.
There is an optional holder for SD Cards. The SD Card holder clips into the base, but you might need to superglue it in place.
You can install a couple of optional 6x2mm neodymium magnets to help hold the base in the box.
The camera grip is tall enough that there is a circular hole in the baseplate so it will fit inside the box and so it doesn't rattle around inside.
There are two holders to support the 75mm extension so it doesn't rattle around inside.
