This specially designed holder fits a 'Dell Venue 8 Pro' tablet. It allows you to securely mount a USB OTG cable to the body of the device to avoid strain on the small mini-USB port. By preventing damage to the port, which is also used for charging, it extends the life of the holder.
In addition, a hole has been added for storing different stylus pens. The hole is designed to fit a Jot Pro, but other pens can also fit. The size of the hole can easily be changed in the OpenSCAD file.
The holder is designed for use with this USB OTG cable, but other cables may also fit or you can customise OpenSCAD: http://www.amazon.com/gp/product/B005QX7KYU/
