Like most other Wolf Pup owners I did not have a need for the equipped Bluetooth speaker mount. While the two USB ports are a good touch the mount is big and useless without the speaker, which is too pricy. So I put together a quick design to transform the speaker mount into a phone holder. It fits many smaller phones with the total spacing 12mm x 73mm. A pixel 4 is shown.

Now available as a TV remote mount!

Printed at .25mm height and with all supports.
