Oil where it belongs.

Fifteen laser-cut parts and four hinged trap doors that let oil in and keep it there — so the pickup stays covered through every long, loaded corner.

02 — Anatomy

Fifteen parts.
No wasted ones.

A flat top plate locates on the pan rails. Two folded side plates form the box around the pickup. Four doors hang on captive pins — they swing in, never out.

    Same corner.
    Different pan.

    Two pans, the same litre of oil, the same 1.5 g thrown at them one way and then the other. Watch the oil around the pickup in the stock pan leave, and the box on the right hold on to its share.

    04 — Function

    Corners push oil away.
    The doors push back.

    Under sustained lateral load the oil climbs the outside wall of the pan. The doors on the loaded side swing open and let it flood into the box; when the load reverses they close, trapping it around the pickup.

    05 — Detail

    Cut, folded, signed.

    Every edge comes off the laser. The name goes straight through the plate — not a sticker, not a print.

    Drawn before it's cut.

    Every Ahura part starts as a fully-defined model in Fusion. Here's a look at the general arrangement — production drawings stay in the workshop.
