This is the second version. My first grille, drawn before I realised it was choking the engine, had a dense honeycomb; this one keeps its outline, frame and mounting tabs but opens the honeycomb up so the intake breathes freely, and its deeper bars are stiffer than the old ones.\nAirflow # The frame rests on the snorkel head, so only the opening inside the frame counts.\nMy old grille This grille Open area inside the frame 7 350 mm² (55 %) 10 480 mm² (77 %) Jet contraction coefficient¹ ≈0.69 ≈0.80 Effective flow area ≈5 070 mm² ≈8 400 mm² vs. a 3″ pipe (4 560 mm²) ≈1.1× ≈1.8× Mass (1.29 g/cm³) 67 g 54 g ¹ Estimated as Cc = 0.63 + 0.37·f³ (f = porosity). These are estimates, not a flow simulation. Pressure loss scales with (pipe area / effective area)², so this grille loses roughly 2.5× less than the old one. A rule of thumb for intake screens is an effective area of 1.5–2× the duct.\nStrength # Honeycomb bars are 1.6 mm wide but 8 mm deep. In bending that is stiffer than the old grille\u0026rsquo;s 3 × 5 mm bars (1.6·8² = 102 vs 3·5² = 75), while blocking much less of the opening. The frame, the honeycomb, the logo ring and the letters are all 8 mm thick, so the whole grille is one flat, rigid plate. The lettering is carried by the honeycomb itself: the grid is shifted half a row so the zigzag between rows runs through every letter. Fit # Plate 144.4 × 103.15 mm (152 mm over the tabs), corners R12.7 — checked on a printed part against the snorkel head. Nothing sticks out at the back: the honeycomb is flush with the frame, so the grille goes all the way into the snorkel head. Tabs 3.8 × 57 mm, 22 mm high, with a Ø5 hole for the fasteners; outer corners and back edges rounded R1. Logo: NISSAN in a 2.5 mm ring Ø72, letters 14 mm high. Printing # Print face down (as the file lies), tabs up. No supports needed. Use a 0.4 mm nozzle: 4 perimeters fill a 1.6 mm bar completely. The meshes are checked to be watertight.\nFiles # nissan-patrol-y60-snorkel-grille_3D_model.stl — for printing nissan-patrol-y60-snorkel-grille_3D_model.3mf — for printing, clean (no slicer profiles) nissan-patrol-y60-snorkel-grille_3D_model.step — solid model for editing License # CC BY 4.0 — do whatever you like with it (copy, change, sell), just credit the original author: Eugene Vereshchagin (github.com/eugene-vereshchagin).

Modelled from scratch in SolidCraft as a single solid. The reference was the mesh ref/nissan_logo.stl scaled ×1.1 and measured point by point; the ring was then made 6 mm smaller in diameter and the bar 2 mm larger all around.\nGeometry # Ring Ø103.6 mm, bar 134.6 × 37 mm, overall height 13.83 mm. The bottom is one flat plane. Ring (revolved): 1.1 mm outer wall, 45° slope up to an 8.4 mm ridge (r 43.2–44.5), 1:3 inner slope, slanted window wall; window Ø68.8 mm at the base. Bar: arched top R≈266 (13.83 mm at the centre). The ends copy the ring\u0026rsquo;s outer side — 1.1 mm wall and 45° slope, blended into the dome with R3. In plan it narrows towards the ends; corners are rounded (R4 at the ends, R32 and R152 at the bends). Lettering NISSAN in the Nissan Opti font (_fonts/, free for personal use, fan-made), 18.9 mm high, 106.4 mm wide. Letters for two-colour printing # Every letter floor lies on one horizontal plane at letter_floor_z = 7.2 mm (a parameter; keep it a multiple of the layer height). Letter depth is ≈1.1 mm at the outer letters and 6.6 mm at the centre.\nTwo ways to print it:\nColour change by layer (recommended, only two filament swaps). Use 0.2 mm layers, first layer 0.2 mm too — otherwise layer boundaries miss 7.2 mm. In OrcaSlicer, Preview, vertical layer slider: add a colour change to the second colour at the layer with Z = 7.0 (layer 35) and back to the base colour at Z = 7.4 (layer 37). Layers 6.8–7.2 mm print in the second colour and every letter floor comes out coloured. With one extruder that is an M600 pause and a manual swap; with a multi-material unit the swap is automatic. Side effect: thin coloured rims on the ring slopes and on the bar-end blends. Paint the letter floors with the colour brush in the slicer — no rims, but many filament swaps (one on every coloured layer). Inside the SolidCraft project # Features, the body and the parameters have English names, parameters carry comments, and the part description is stored in the design properties (it also goes into the 3MF metadata).\nKnown limitations # The long top edges of the bar stay sharp: SolidCraft 0.30.1 only blends straight edges, and these follow the dome\u0026rsquo;s arc.
