Description

This is a conversion housing as well as an extension arm for converting the RX-8 throttle to Drive by Cable. Should be pretty straight forward, stock pedal arm will need some modification in the form of cutting away the ''toothed'' inner section of hinge, hole drilled for 10/24 bolt and riv-nut, as well as hole cut for return spring relocation.

Its functional for now, though I am sure there's room for modification. Uses one 10/24 allen head bolt, one 10/24 riv-nut, three m3x12 bolts(your choice of length). Offers about 60mm of cable travel. In my case drives a Holley 92mm throttle body perfectly. testing with PLA+, might be better served using PETG.

STEP & STL.

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.
