Size Run → STL Export

Stock ring + size list → every size generated in Rhino, STL files exported for casting.

The problem

Production runs of a single ring design across multiple finger sizes: 6, 6.5, 7, 7.5, 8, 8.5, 9. Each size = separate Rhino file, separately resized, separately exported as STL for the 3D-printer driving casting. Manually: 20 minutes per size; 7 sizes is 2+ hours and easy to misnumber.

The outcome

Name the design + size list. Claude resizes in Rhino, exports STLs with consistent naming, and confirms wall thickness is above casting minimum for each size.

The prompt

Paste this into Claude (with Cohesive360 installed in your Claude → Settings → Connectors). Replace bracketed placeholders with your specifics.

Take design [DESIGN NAME / FILE]. Run a size run for sizes [LIST, e.g. 6, 6.5, 7, 7.5, 8]:
1. Resize the design to each finger size.
2. Check wall thickness at each size — flag any below 0.8mm.
3. Export each as an STL with name [DesignName]_Size[N].stl.
4. Summarize any sizes that failed the wall-thickness check.

What Claude does

Step-by-step rundown of the work. Every write is drafted, not posted — you approve before anything lands in your systems.

  1. 1

    Open base design

    Claude opens the named design in Rhino. Parametric designs resize exactly; static .3dm files scale geometrically.

  2. 2

    Resize per finger size

    Standard US ring-size diameter conversions; EU/UK conversions if specified.

  3. 3

    Check wall thickness

    Measures thinnest point per size. Flags below 0.8mm casting minimum. Wall thickness drops at smaller sizes; flag is the safety net.

    Export STLs

    One STL per size, named consistently. Ready for the 3D printer's queue.
