    #35 — Linear Rail Endcap

    This folder contains a working example that generates a STEP model for: Endcaps that fit common rail profiles, with optional mounting holes.

    The intent is that you can run the code here to emit a STEP file, open it in a CAD viewer, and/or import it into your slicer to 3D print and iterate.

    #What this example demonstrates

    • precision rail profile fitting
    • integrated mounting features (fastener seats)
    • single-profile complex geometry construction
    • emerald green aesthetic with engraved labels

    #Parameters to try

    • railWidth: Width of the linear rail (e.g. 12 for MGN12).
    • railHeight: Height of the linear rail.
    • thickness: Total thickness of the endcap.
    • clearance: Tolerance added to the rail pocket.
    • seatDiameter: Diameter for the mounting screw.

    #Suggested extensions

    • add a second mounting hole for dual-screw attachment
    • add a wiper groove for a rubber or felt insert
    • add text on the top face with the printer model name

    #Variant 1

    Command line: ./run-example.sh 35 --railWidth 12 --railHeight 8

    #Variant 2

    Command line: ./run-example.sh 35 --railWidth 15 --railHeight 10 --thickness 15
