This stand can be used to place small macro key pads, various music devices, as well as phones, Nintendo Switch, and other devices.
 

I used a tree-like support structure and printed it with a 0.4mm nozzle. Apart from removing the supports, there's no need for any additional hardware assembly or post-processing steps.

This design is specially made for use as a keychain or carabiner, and it can also be easily stored in a small pocket or compartment.

During the assembly process, the smaller triangular components can be easily embedded into the corresponding large components. When storing, you just need to slide the components into the second dovetail groove below and then lock and fix each part. In addition, the design also deliberately provides anti-slip buckles, which effectively prevent the components from accidentally slipping off.
