I made this stand for smartphones. It is created to be 3D print friendly, so no supports required.

Information:

Made with: Blender

Formats: .stl, .obj

Purpose: 3D Printing

Height: 18 cm / 7.08 inches (Resize to your needs)

Infill: 20-25% (More infill means more stability and durability during and after the print)

Supports: No supports needed (Tested on modified Creality Ender-3)

Suggested print speed: 40-60 mm/s (Depending on your printer and how fine it prints)

Textures: Monochromatic

Rigging: None

Additional information: I noticed that my Cura (version 4.8.0) places some models way up high so select the model with Ctrl+A and change the height (Z-Axis) to 0
