Description

This is a replacement for Porsche part 99904902240, also called "plastic nut". This part is used on (at least) the 996 (911) and 986 (Boxster) to secure the underbody covers to the chassis. A 986 has over a dozen of these nuts, they're also used to secure the carpet on the engine cover behind the seats.

The original ones tend to get loose or break over the years, so I needed a few new ones. I designed these using a 10mm nut and adding a round surface around it, to match the original nuts.

Pricing assumptions and exclusions

USD: ($6 setup + $3 finishing + filament weight × assumed spool cost × 1.25 waste allowance + print hours × $2.50 × material time factor) ÷ 0.65. Rounded up to the next $0.50.

Assumed spool costs per kg: PLA $25, PETG $30, ASA $40, ABS $30, TPU $45, Nylon $65, PA-CF $95. Time factors: PLA/PETG 1.0, ASA/ABS 1.2, TPU 1.6, Nylon 1.4, PA-CF 1.5. These are proposed shop rates, not measured production costs.

Design work, test fitting, hardware, shipping and tax are additional where needed. Multi-file sets may need several prints. Use actual sliced weight and time when available. Final pricing is confirmed in writing.
