parametric-calibration-objects

A library of parametric OpenSCAD calibration objects for 3D printers. Each file in src/ is a reusable library module -- no geometry is generated on include, only on an explicit module call. Example entry points live in examples/.

Modules

Module	File	Description
generate_bed_level_pattern(...)	src/bedlevelpattern.scad	Bed levelling test patterns (8 pattern types)
generate_flow_tower(...)	src/flowtower.scad	Flow / extrusion multiplier calibration tower
generate_temp_tower(...)	src/temptower.scad	Temperature calibration tower (bridged style)
generate_temp_tower_detailed(...)	src/temptower_detailed.scad	Temperature tower with detailed section geometry
generate_retract_tower(...)	src/retracttower.scad	Retraction distance calibration tower
generate_speed_tower(...)	src/speedtower.scad	Print speed calibration tower (L-shaped, XY axes)
generate_xyz_cali_cube(...)	src/xyzcalicube.scad	20 mm XYZ calibration cube
generate_torture_test(...)	src/torture_test.scad	Structural torture test model

Usage

Each library module is used with include + a module call. Example:

include <src/temptower.scad>;

generate_temp_tower(
    tower_label = "Temp",
    starting_value = 220,
    ending_value = 180,
    value_change = -5
);

Ready-to-use example files for every module are provided in examples/:

examples/
  bedlevelpattern_examples/   -- bed level pattern examples (8 patterns + showcase)
  flowtower_examples/         -- flow tower example
  retracttower_examples/      -- retraction tower example
  speedtower_examples/        -- speed tower example
  temptower_examples/         -- temperature tower examples (standard + detailed)
  xyzcalicube_example.scad
  torture_test_example.scad

Quality / rendering

All examples set $fn based on $preview:

$fn = $preview ? preview_quality_value : render_quality_value;

Lower values render faster in preview; increase render_quality_value before exporting for final STL output.
