🔄 Inception — HomeRacker Meta

📌 What

Models for organizing HomeRacker parts within the HomeRacker ecosystem. Includes Gridfinity-compatible bins and frame-mounted grids for storing supports and other bits.

🤔 Why

For the completely insane people who want to store their leftover HomeRacker parts in an organized fashion — on a HomeRacker shelf, in Gridfinity bins, of course.

🔧 How

Open any file in parts/ with OpenSCAD and use the Customizer panel.

Support Bin

A Gridfinity bin with a pocket grid that holds HomeRacker supports upright. Uses a standard Gridfinity bin base.

Parameter	Default	Range	Description
`grid_x`	2	1–17	Gridfinity units in X (×42 mm)
`grid_y`	2	1–10	Gridfinity units in Y (×42 mm)
`divider_strength`	1.2	1.0–3.0	Divider wall thickness (mm)
`grid_style`	Riser	Riser / Full	Cross-shaped ridges vs solid walls
`height`	15	5–15	Pocket grid height (mm)

Grid styles:

Riser — Cross-shaped ridges with 45° slopes; minimal material, easier fitting
Full — Solid walls with rectangular pockets; maximum rigidity

Support Grid

A frame-mounted pocket grid that clips directly into a HomeRacker rack opening via mounting ears with lock pins. No Gridfinity base needed.

Parameter	Default	Range	Description
`hr_width`	11	15–17	Frame width in HR units (×15 mm)
`hr_height`	3	3–10	Frame height in HR units (×15 mm)
`end_piece`	false	true/false	Add backstop to prevent supports sliding through
`funnel_strength`	3	3.3–5.0	Divider wall thickness (mm)
`grid_depth`	1	1–5	Grid depth in HR units (longer = more stable)
`mounting_axis`	Vertical	Vertical / Horizontal / Both	Where to place the mounting ears

Mounting axis options:

Vertical — Ears on the left/right sides of the grid
Horizontal — Ears on the top/bottom
Both — Ears on all four sides
