Original Mechanical Phone Holder Desk Mounted Stand Arm.
It secures your phone in a desired position using gravity. 

You can find assembly instructions attached as a PDF document below.
 

The holder could be mounted to the desk up to 50mm thick. You can print as many arms as you like to have a custom stand. All the joints could be adjusted. The front part is available in two versions: with and without the logo. The logo version can be found on a separate plate.

It is strongly recommended to use the profile created by the designer because it applies custom supports and different wall loops for the parts that require more strength.

The gravitational mechanism requires additional parts such as:

• 8pcs of BT2.6x8 SHCS Self Tapping Screw - AA004 (don't try to use longer screws it may prevent the mechanism to work correctly)
• 1pcs of 1.4x20mm Basic Rubber Bands - RA002

You can easily find those parts as well as the filament used in the Bill of Materials.
