Screw-clamped arms for capturing angles of internal and external corners. Prints as three pieces: Top, Bottom, and Screw.
To use after printing and assembly: Loosen Screw slightly so the Top arm floats between the Bottom and head of Screw, adjust arms to sit flat against angle being measured, secure Screw with arms in-place, trace the same angle onto your work.
The author marked this model as their own original creation.
