simple smartphone holder stand with space for 1/4" screw

Designed this simple stand for my smartphone holder.

Rectangle hole in the middle of the model is for velcro in case you want to strap the holder onto some object and take video/photos from there.

It will fit various stands that have ¼" screw (screws can be ordered from ebay).

- layer height: 0.3mm
- nozzle diameter: 0.6mm
- print orientation: as in the STL file
- material: PETG
- supports: not needed
