Sample Mounts

3D-printable sample mounts (scroll cases, interface plates, spindles, and trays) for scanner and beamline data acquisition.

User docs: https://educelab.github.io/sample-mounts/

Models

Ready-to-print STLs. Variants are named after the parameters they were rendered with (e.g. SpindleBase-6.35mm.stl, SI Interface Plate - 200mm.stl).

• Mount discs and rings. The standard base (Generic Mount Disc, and a 65 mm version) and the ring it mates with.
• Interface plates. Adapt the mount disc to a specific scanner or beamline stage (SkyScan 1273, I12.EH1, SI).
• Spindles. Spindle bases and stoppers for several rod diameters.

OpenSCAD

Parametric sources for the models. Parameters are top-level variables and can be overridden on the command line:

openscad -o out.stl -D rod_type=2 "OpenSCAD/Spindle Base.scad"

Interface plates and spindle bases are built on Generic Mount Disc*.scad, so changing the disc changes all of them.

Fragment Trays.scad and Hanging Frame Case.scad depend on Diamond Interface Plate.scad, which isn't in this repo, so they won't render as-is.

scrollcase

Python generator for split scroll cases fit to a scroll mesh. Requires uv:

cd scrollcase
uv run scrollcase defaults --style educelab.v1 > my-scroll.toml
uv run scrollcase build -c my-scroll.toml -o out/

See Creating a scroll case and the config reference.

utils

SpiralLength.cpp computes the length of an Archimedean spiral for use with Spiral Frame.scad. It needs GSL:

cmake -S utils -B build && cmake --build build
