I secured the new OpenDendrometer prototype to the tree in my backyard this afternoon. The plan is to collect data over the next couple of days.

This new mechanical design includes some features that increase the rigidity between the tire depth gauge and tree. These should improve the device's ability to detect micrometer changes in tree diameter. Changes include: no longer using a 3D printed enclosure (so no material softening at 30°C), two threaded rods to anchor to the tree (previously was only using one), and a metal shaft collar at the probe tip (previously was a 3D printed tip).

Excited to see the data!
