Locus tactile graph graph-6-v1
Braille ID on the plate: G6

How to print
- Open graph.stl in your slicer. The units are millimetres.
- Print at 100% scale. Do not resize it: the touch checks measured the spacing at this size.
  In the slicer the part must measure 100.0 x 100.0 x 3.6 mm.
- Lay it flat on the bed, as it is in the file. The prototype prints used PLA, 0.12 to 0.16 mm layers and no supports.
- Hold the plate with the triangle at the top-left. The braille ID is at the top-right.

Files
- graph.stl: the plate to 3D print
- graph.svg: the same graph seen from above, in millimetres
- overlay.svg: what the touch checks measured, drawn on the graph
- description.txt: a text description of the graph for the learner
- touchcheck-report.json: touch checks TL-1 to TL-5, passed after 2 attempts
- manifest.json: where this bundle came from: commit, pipeline, file hashes and checks

Limitations: Automated checks measure spacing and size; they do not certify that a learner can understand the graphic.
