All Grids & Gauges Generators
1:1 Isometric & CAD Grid
1:1 Printable Isometric Grid, Hex Pattern & CAD Calibration Sheet Generator
Standard printable graph paper PDFs found online are rasterized or scaled to fit printer margins, destroying true millimeter accuracy. Whether you are sketching 3D isometric packaging prototypes at 30-degree projection angles, laying out tabletop hex maps, or engraving a permanent 10mm alignment grid onto your laser cutter's honeycomb spoilboard, you need a mathematically exact 1:1 vector grid. Our parametric generator creates true-scale isometric and orthogonal coordinate grids with a dual 50mm / 2.0-inch verification ruler.
1:1 Hexagonal Honeycomb Grid
1:1 Hexagonal Honeycomb Grid, Tabletop Wargame Map & CNC Airflow Mesh Generator
Hexagonal honeycomb grids serve two critical engineering roles: 1:1 tabletop wargaming and RPG map sheets (where standard miniature bases require an exact 25.4mm / 1.0-inch flat-to-flat hex pitch) and high-airflow CNC/laser-cut electronics ventilation grilles (where a 3.0mm structural web bridge separates adjacent hexagonal cutouts). Unlike naive CAD arrays that stack duplicate shared edges and cause laser cutters to burn the same line twice, our generator computes independent closed hexagons spaced by a structural web bridge so every cell cuts cleanly in a single pass.
Circular Fan Grille & Speaker Mesh
Perforated Circular Fan Grille, Speaker Mesh & Acoustic Baffle Plate Generator (DXF & SVG)
Designing a high-airflow PC fan grille (80mm, 120mm, 140mm, or 200mm), audio speaker mesh, or industrial electronics vent plate requires balancing open-area airflow percentage against structural web stiffness and ISO 13857 finger safety. Our parametric generator creates a corner-chamfered square mounting plate with 4 corner M4/M5 fan mounting holes at your exact bolt pitch (W), then populates the circular airflow aperture with concentric 60-degree staggered rings of closed circular perforations (diameter = H) separated by a rigid 3.0mm structural web bridge.
Industrial Bridged Stencil Plate
Laser-Cut Industrial Bridged Stencil Plate & Spray Marking Template Generator (DXF/SVG)
When laser-cutting stencils out of Mylar film, polypropylene, or stainless steel sheet, any closed loop inside a character or symbol (such as 0, 4, 6, 8, 9, A, B, D, O, P, Q, R) will fall out completely unless connected to the surrounding plate by structural stencil bridges. Our parametric bridged stencil plate generator creates a reusable industrial marking plate (`L × W`) with a minimum 25mm overspray border guard, V-notch horizontal baseline alignment sights on the left and right edges, corner hanging holes, and island-bridged upper and lower stencil apertures.
