Delrin Style M10 x 1.25 mm Shift Knob

Miata Delrin Style Shift Knob – M10x1.25

A simple, clean circular shape with flare shift knob is designed to let you test your preferred shape and height before committing to an expensive aftermarket option. This model has confirmed fitment on the ND Miata and uses the common M10 x 1.25 mm thread pitch, making it compatible with most other Miatas and many additional vehicles. This design is very, very similar to the Flyin' Miata's Delrin shift knob. Please check out my other shift knob 3D models for other options!

Recommended Materials for Long-Term Use

Vehicle interiors can get extremely hot and see heavy UV exposure. For durability, use:

• ABS
• ASA
• PETG / PET
• Nylon

PLA is great for test fitting but may soften over time in high cabin temperatures.

🎨 Design & Customization

• Clean cylindrical profile
• Minimalist aesthetic
• Lightweight and customizable
• Great for experimenting with height and diameter before buying an aftermarket knob
