Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:5935499.

This stand holds the PineTime charging cradle at a 5 degree angle from vertical and directs the USB cable out the back. The charging cradle snaps in from the back, and can be removed with difficulty but without damaging the cradle or stand.

You can fork this design on Onshape here.

I have a blog post with additional pictures here.
