10 Inch Rack Generator

OpenSCAD file to generate a 10 inch rack for 3d printing

My Presets

My personal model configurations are saved as Customizer presets in 10InchRackGenerator.json. OpenSCAD auto-loads this file (it shares the .scad basename), so each saved model appears in the Customizer's preset dropdown — pick one, Render (f6), then export the STL.

To build a preset from the command line:

openscad -p 10InchRackGenerator.json -P "Xyber Hydra" -o out.stl 10InchRackGenerator.scad

Every saved preset is also covered by the test suite (see the customizer presets render case below), so presets added via the Customizer get rendered automatically with no test edits.

Testing

Manual Testing

1. Open OpenScad
2. Modify variables
3. Click 'Render' button (f6)

CLI Testing

1. openscad -o foobar.stl 10InchRackGenerator.scad

Automated Tests

Requires bats-core, openscad, and jq (used to read presets) on your PATH.

# Fast preview tests — renders PNG images, ~1s per case
make test

# Full geometry validation — renders STL files via CGAL, ~35s per case
make test-stl

# Run a single test by name
make test TEST=missing_air_holes

# Run a single test with stl
RENDER_STL=1 make test TEST=missing_air_holes

# Render every model saved in 10InchRackGenerator.json
make test TEST="customizer presets render"

The customizer presets render case reads 10InchRackGenerator.json at runtime, so any model you save from the GUI Customizer is tested automatically — no test edits needed.

Output files land in tests/renders/. Each test case produces up to five PNG previews:

tests/renders/
  default_corner.png
  default_front.png
  default_side.png
  default_top.png
  default_bottom.png
  default.stl          ← only present after make test-stl

To run a specific named case and also get its STL alongside the PNGs:

make test TEST=dell_optiplex_7020
# → tests/renders/dell_optiplex_7020_{corner,front,side,top,bottom}.png
# → tests/renders/dell_optiplex_7020.stl

Keystones

An openscad file to generate keystones is avilable on makerworld A stl is available at ./keystone.stl and ./keystone.3mf
