This project is a mounting system for lightweight objects such as phones and small cameras.

MAJOR V5 UPDATE [27/07/19]:
- Visually slimmer arms with curved profile and more uniformed strength. More friendly for printing orientation.
- More tolerance at tab connections.
- Rotating phone clamp to quickly switch between horizontal and vertical orientation.
- Added lock to phone clamp holder to prevent sliding.
- Stronger C-Clamps.
- Flat stand with better aesthetics.
- Added assembly diagram for several applications.
- Updated links in useful parts.

FEATURES:
- It is designed to be modular to provide flexible use. The system has potential to mount most phones and small cameras onto a wide range of objects. Using same parts printed for different purpose is the major approach.
- The included phone clamp can grab phones very firmly. And it is suitable for phones from about 55mm wide to 85mm wide (iPhone 4 - iPhone XS Max and bigger). The clamp hook was angled so it won't be able to reach and accidentally press the buttons on the side of phone.
- The modules can be used with GoPro compatible equipment. The bolts and nuts included in the design are standard M5. It's recommended to use metal bolts and nuts for the arm.
- With this modular system, I will be developing new add-ons to it. Feel free to watch this thing. Many of the objects designed for GoPro are already usable for this setup. I uploaded some STEP files for modular parts so everyone can also collaborate for better solutions.

ACHIEVED APPLICATIONS:
- Phone/Camera/GoPro mount for Ultimaker 2 monitoring.
- Phone/Camera/GoPro mount for Aluminum extrusion printers.
- Desk clamp for phone/camera.
- Stand for phone.
- Headphone stand.

MAKING:
- It is highly recommended to print with complete support interface for the parts in this project. Support interface would give a flat bottom which result in a better mechanical performance.
- The orientation of stl files are already thought through during my testing. Try printing at the current orientation unless you run into problems. It is not recommended to reorient the arms to save support material. The tabs will be easy to break if printed otherwise.
- Mirror the arm one after another in order to have knobs on the same side.
- In order for the bolts to be strong enough to take pulling force, they cannot be printed vertically. Therefore the bolts are oriented horizontally, with the bottom teeth trimmed off, and with 30 degrees step shape (it is usually 45 if printed vertical). With such treatment the bolts are both strong and easy to print with support material even at 0.2mm layer height.
- Print bolts and nuts at low outer wall speed (15mm/s) to increase accuracy. If the tolerence for bolts and nuts doesn't workout for you, try change XY compensation setting in slicer to get a larger tolerance. I've also attached the settings used to create them so you could make your own with slightly altered values.

NOTES:
- It is not recommended to extend the arm too long. General filament is not strong enough to take that much lateral load at this size and the arm would be very wobbly. And the arms are optimized to stay still. If you wish to use this design as selfie stick or similar purpose, please be careful with the material strength and use at you own risk.

ACKNOWLEDGEMENTS:
- The joints are inspired by GoPro design.
- The foldable arm is inspired by "GoPro counter balance folding stick. by UltiArjan".
- Bolts and nuts are created with the awesome customizer "NUT JOB | Nut, Bolt, Washer and Threaded Rod Factory by mike_mattala".
- The desk clamp is inspired by "G-Clamp fully printable by johann517".
Thank you all for your great work so that I could accomplish this project.
