Estuche de viaje impermeable para bujías - NGK LMAR8A-9 (Tenere 700 / Africa Twin)

Never get stranded in the wild with a fouled or broken spark plug!

This is a rugged, 3D-printable protective case specifically designed for the NGK LMAR8A-9 spark plug, which is standard for the Yamaha Tenere 700 (CP2), Africa Twin 1000/1100, and many other adventure bikes.

Key Features:

100% Waterproof: Features a dedicated groove for a 20x3mm O-ring, ensuring your spare plug stays dry and corrosion-free even during deep river crossings or heavy rain.

Electrode Protection: The internal geometry is designed so the spark plug seats firmly on its hexagonal nut. This keeps the delicate electrode suspended, preventing the gap from being closed or damaged by vibrations and shocks during off-road riding.

Compact & Tough: Designed to be tossed into your toolkit or strapped to the bike frame without taking up unnecessary space.

Easy Grip: The cap features a knurled texture for easy opening, even with greasy hands or gloves.

Technical Specifications:

Compatible Plug: NGK LMAR8A-9 (and similar dimensions).

Required Hardware: 1x O-ring (20mm ID x 3mm thickness).

Recommended Material: PETG, ASA, or Nylon (for heat and chemical resistance).

Print Settings: 0.2mm layer height, 3-4 walls for maximum durability. No supports needed.

Perfect for ADV riders, world travelers, and enduro enthusiasts who need peace of mind when riding far from civilization.

Recommended Print Settings
To ensure your spark plug stays protected even in extreme conditions, follow these guidelines:

Don´t forget to place the parts correctly on your print bed, to avoid the need for supports.

Material: * PETG: Minimum requirement. Good chemical resistance and decent heat deflection.

ASA/ABS: Best choice. High UV resistance (won't degrade in the sun) and higher heat resistance for those hot engine bays.

Note: Avoid PLA, as it may soften or warp if left in a hot pannier or near the engine.

Layer Height: 0.16mm - 0.2mm. Finer layers help with the smoothness of the threads.

Wall Count: 3 to 4 walls. This ensures the case is rugged and the threads are strong enough to compress the O-ring.

Infill: 25% - 40% (Gyroid or Grid recommended for structural integrity).

Supports: Not needed. The model is designed to be printed with the main body opening facing up and the cap's flat side on the bed.

Post-processing: Apply a tiny bit of silicone grease or motor oil to the O-ring and threads for a super-smooth, airtight seal.
