Overview
This is a fully adjustable phone mount using a ball and socket joint compatible with any type of filament requiring minimal support material aimed to be printed with any FDM 3D printer.

This mount is designed to be compatible with vertically mounted phones with a width of 5.72 cm (2 ¼”) up to 10.8 cm (4 ¼”). This includes the smallest phones such as iPhone 13 mini to the largest phones such as Samsung Galaxy S22 Ultra with a case.

The mount can be attached to a cylindrical bar with a diameter of 0.8” to 1 ¼” which can be found on bikes, scooters, motorcycles, snowmobiles, jet skis, ATVs, etc. using two #6 or #8 bolts and nuts.

A zip tie or thread can tie the Main Holder part to the handlebar using the hole on the side. This hole was added as a safety net to prevent the phone from getting damaged in an event of a failure.

Based on your application, you may have to increase the infill and perimeters (walls). For example, if you are going to use this on a city bike you should be fine with the current settings. But, if you are going to use this on a jet ski or mountain biking, you should consider strengthening the pats, especially the ball part.

Based on the feedback received, I have decided to redesign the parts to make them more durable. Major improvements are the larger cross-sectional area and the removed neck area of the Ball part. The Joint Nut, C Clamp, and Socket Joint were also scaled up to match the Ball. Minor improvements include removing the fillets that made contact with the base plate of the printer and increasing draft angles to 60° to improve the print quality. The Joint Nut fillet's radiuses were also decreased to increase the grip and aid in fastening.

Warning:
There is currently no solution implemented to counteract the loosening effect due to vibrations nor has there been an incident reported. I highly recommend refastening the nuts before every use. Take advantage of the safety-net feature explained previously. Lastly use a decent phone case in an event of a failure. If you face any issues and or have design improvements, please comment below.
