NP1 Base Model

The numpad block from PgUp rightward, built as exact solids on the OpenCASCADE kernel from the firmware's key layout. Drag to turn it, scroll or pinch to zoom.

The zip holds np1.step and np1.igs (solids for SolidWorks, Fusion and Inventor), np1-plate.dxf (the plate cut profile), np1.stl, params.json with every dimension graded, and a README. Native .sldprt and .f3d are saved from inside those apps.

What it is

Size: 81.9 × 131.0 × 40.0 mm
Key field: 76.2 × 119.7 mm (4 × 6 at 19.05, the top row 5.4 mm apart as on the ROG)
Shape: a wedge with floating keys: 15 mm at the case front (your cloth tape), 40 mm at the back keycaps (published), 4.4° typing angle
Feet: 2 flip-out feet at the back, 3 positions: 4.4°, 6.3°, 8.2°
Foam: plate 1.5 · silicone plate foam 1.5 (a thin sheet under the plate, as in ROG's exploded view) · switch pads 0.5 · PCB 1.6 · case foam 2.5 mm
Underside: a smooth back panel for the label and feet, diagonal ribs along the front and sides, and a rubber strip on each foot (as on ROG's bottom view)
Switches: 19 hot-swap ROG NX Snow (refined linear, 1.8 mm, 40/53 gf), your pick for the White Base; NX Storm (refined clicky, 65 gf tactile) shown for comparison
Keycaps: mid-height, similar to Cherry profile (ROG); modelled flat until measured
Stabilizers: 3 ROG pre-lubed, plate-mount, at 23.8 mm
Wheel: knurled roller 19.2 × 15.3 mm (measured on ROG's top view), its encoder under the badge housing
Parts: 81 solids, feet folded in the STEP
Formats: STEP, IGES, DXF, STL
Kernel: build123d 0.13.0 · OpenCASCADE

Exact: MX pitch, 14.0 mm cutouts, 1.5 mm plate, 1.6 mm PCB, MX pin holes, USB-C opening, and ROG's published 131 × 40 mm. Measured: the side frame and keycap sizes (ROG's photo, ±1.5%) and the front height (your cloth tape, ±2 mm). The model's front keycap top is 31.2 mm; your side tape reads 29.5 ± 2.
