After breaking almost uncounted iphone usb cables!! I designed this using Fusion 360 to save my newly purchased charging cables.

Download Fusion 360 http://www.autodesk.com/products/fusion-360/overview

Notes:-

• Scale the design by x1.1 if you find difficulty in fitting.
• I haven't tried printing it with different materials, specially flexible material like ninjaflex. Keep me posted if anyone prints it in different material.
• If you want to update or modify the design then I wont mind sharing the original .f3d files, ping me if you need it.
• I would be more than happy if you share this design within your network so that more people can 3D Print it and save their charging cables.
• Do not forget to tag me while doing a social media shoutout @varunheta

Recommended settings for decent quality 3D prints:

• Layer height: 0.2mm
• Infill Density: 15%
• Shell Thickness: 0.8mm
• Material: PLA or ABS
• Print Speed: Not more than 40mm/s
• Supports: No
• Orientation: Upside Down Vertical Position
• Rafts: Yes

Let me know if there is anything else you would like to know about the design. I am more than happy to assist you all. Cheers
