ZTE Speed Holder for FTC

This is a 3D printable holder for the cheap ZTE speed Android phone, designed for use on FTC robots. With the new control system in FTC, they give us these phones, but no good way of attaching them to the robot or securing the USB cord. I designed this part to solve this problem for my former FTC team, 4278 De.Evolution. Unlike the holder in the kit-of-parts, it fits around the whole phone and locks it in place securely.

It has a USB cable strain relief (sized for the white Modern Robotics OTG cable, but should fit most other cords), and holes spaced for a TETRIX beam on the side plates. It also has cutouts for the volume and power buttons, the speaker, the microphone, the camera, and the headphone jack.

This holder has several different mounting options. You can mount it to a tetrix beam using the provided holes, or you can mount it to something else by drilling your own holes wherever you want in the side plates. You can also zip tie it on, or you can use ABS cement t
