HomeRacker Modular Plate – Parametric

A plain, configurable plate for the HomeRacker 15 mm grid system.
Size, edge holes, corner cut-outs, fan grills, and split-printing are all set in the Customizer. No hardware beyond 4 mm dowels (lock pins) or printer filament is required.
Print one solid panel or slice it into inter-locking pieces if your bed is smaller than the plate.

Features

• Adjustable Size: Width and height in 15 mm HomeRacker grid units (2–25 units each).
• Variable Thickness: Plate thickness from 1 mm to 5 mm.
• Edge Holes: Left / right / top / bottom edge holes that follow the HomeRacker 4 mm lock-pin pattern.
• Hole Skip Intervals: Set per-edge skip intervals (e.g., enable every 2nd or 3rd hole).
• Middle Hole Lanes: Configure up to 5 vertical and 5 horizontal lanes of holes in the middle of the plate, each with independent position and skip settings.
• Corner Cut-outs: Optional L-shaped cut-outs at each corner (toggled independently) with user-set arm length and width.
• Corner-Edge Holes: Automatically adds a hole at the corner edge when the matching cut-out is disabled.
• Edge Cut-outs: customizable cut-outs on all four edges (left, right, top, bottom):
  – Configure count, dimensions, spacing, and offset for each edge independently.
  – Selectable shapes: rectangle, rounded rectangle, or semicircle.
