Description

This is a shift knob that I designed for my 1999 Mazda Miata. I tired to replicate the feel of a stock NB shifter, and it definitely feels similar. I wanted a shifter to compliment my short throw. The thread pitch is M10 x 1.25 so it could potentially fit 240sx's. I made a 1/4" diameter (4" long) hole in the center of the shifter to press fit a steel rod into the knob, however it will most likely need to be drilled out to a larger diameter if you intend on installing the rod. You will need a very long drill bit. I ran my shifter without a rod with no problems.

Also, one more thing. Please be mindful that PLA will most likely melt in the sun. Use ABS.

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.
