SHIFT NOVA V3 HYPERFLOW

Adaptive Grip Pro — Modular Racing Shifter Knob Concept for Thrustmaster TH8S

ONE CORE. THREE SIZES. YOUR SHIFT.

🏎 Meet SHIFT NOVA

What if your gear shifter could adapt to your hand instead of forcing your hand to adapt to it?

Introducing SHIFT NOVA V3 HYPERFLOW, a futuristic, modular gear shift knob concept designed for sim racing enthusiasts who value ergonomics, customization, and innovative 3D printing.

Inspired by high-performance turbines and motorsport engineering, SHIFT NOVA combines an aggressive racing aesthetic with an interchangeable grip system.

Its defining feature is the Adaptive Grip S/M/L System.

Instead of printing three completely different shift knobs, users can choose between three grip sizes using a single central body and interchangeable outer shells.

SHIFT NOVA is more than a visual redesign. It explores a new approach to customizable sim racing hardware.

1. Adaptive Grip — Three Sizes, One Core

The heart of SHIFT NOVA is its modular grip system.

A traditional gear shift knob has a fixed diameter. SHIFT NOVA introduces three configurations designed around different grip preferences.

The S configuration provides the original sculpted turbine surface.

For additional grip volume, users can install the M or L shells around the central body.

Each configuration retains the distinctive HYPERFLOW design language.

One central body. Multiple grip configurations.

2. Hyper Turbine — Designed to Stand Out

SHIFT NOVA takes its visual inspiration from jet turbines, high-performance racing components, and futuristic mechanical design.

The outer surface features flowing spiral structures that create a dynamic sense of motion.

Unlike purely decorative designs, the turbine geometry is integrated into the ergonomic shape of the knob.

Additional design elements include:

Exoskeleton Surface: Mechanical armor-inspired reliefs integrated directly into the grip shells.

Energy Channels: Recessed details that can be highlighted using contrasting colors.

Hexa Grip: Fine geometric texture for additional tactile feedback.

Asymmetric Flow: A sculpted profile that supports different hand positions during shifting.

Thumb Control Zone: A dedicated contact area designed for comfortable thumb placement.

The goal is a recognizable, futuristic design that remains practical to hold.

3. Quick Swap Grip System

SHIFT NOVA's interchangeable grip shells use an integrated mechanical fastening concept.

Each M and L grip consists of two separate halves.

The halves surround the central body and connect through snap-fit features.

The system is designed around four key principles:

1. Interchangeable grip sizes without replacing the entire shift knob.

2. Mechanical fastening without permanently gluing the grip shells.

3. Shape-based positioning to reduce unwanted rotation.

4. Accessible assembly and removal.

The Snap-Lock 2.0 concept includes alignment features and a mechanical click intended to provide feedback during installation.

Development note: Snap-fit retention strength, repeated assembly durability, and resistance to movement during shifting still require physical testing.

4. Signature Top Collection

Personalization extends beyond the grip itself.

SHIFT NOVA features a modular top cover designed to accept interchangeable emblems.

The design collection includes:

Turbine Edition — A stylized turbine emblem.

Gear Pattern Edition — A motorsport-inspired shift pattern.

Racing Number Edition — A customizable racing number.

Minimal Edition — A clean design for a subtle appearance.

The removable top system allows users to change the character of the shift knob without redesigning the main body.

5. Customization Without Multi-Material Printing

SHIFT NOVA is designed as a collection of separate printable components.

This allows users to combine colors without requiring a multi-material 3D printer.

Suggested color combinations:

The main body, accent collar, grip shells, and top emblems can be printed separately.

Energy Channels can also be highlighted using suitable paint or finishing techniques.

6. Smart Internal Structure

The central structure has been developed with material efficiency and stiffness in mind.

The design incorporates internal lightening features while retaining material around critical structural areas.

Its main objectives are:

• Maintaining a stable central structure.

• Reducing unnecessary material consumption.

• Preserving adequate wall thickness.

• Strengthening areas around mechanical connections.

• Avoiding unnecessarily complicated internal cavities.

Design-surface sampling identified approximately 1.59 mm minimum radial shell thickness in the M grip and 1.70 mm in the L grip.

These are preliminary geometric measurements, not laboratory strength-test results.

7. Designed for Accessible FDM Printing

SHIFT NOVA is developed with desktop FDM printers in mind.

The geometry aims to minimize difficult overhangs, reduce unnecessary support material, and allow components to be printed separately.

Suggested starting print settings

These are preliminary settings for prototype printing.

The snap-fit components are especially sensitive to material properties, print orientation, and dimensional accuracy.

Support-free printing has not yet been physically verified for every component.

8. Print-Fit Calibration System

Different printers and filaments produce slightly different dimensional results.

To make fitting easier, SHIFT NOVA includes small calibration components.

Snap-fit test samples are provided with three nominal clearances:

• 0.20 mm

• 0.30 mm

• 0.40 mm

Users can test these samples before printing the complete grip shells.

The project also includes S/M/L size-testing rings for an approximate comparison of grip dimensions.

This approach is intended to reduce wasted filament and make the modular system easier to calibrate.

9. Assembly Concept

The modular system is intended to be assembled in the following order:

Step 1 — Prepare the central body

Check the printed main body for dimensional accuracy and surface defects.

Step 2 — Select your grip size

Use the original body for S, or select the appropriate two-piece shell for M or L.

Step 3 — Align the grip halves

Position the two halves around the central body using their alignment features.

Step 4 — Engage the snap connections

Carefully join the halves without applying excessive force.

Step 5 — Verify retention

Check that both halves are properly seated and cannot move unexpectedly.

Step 6 — Customize the appearance

Install the selected top emblem and decorative accent components.

Before use, verify that every removable component is securely retained.

This assembly procedure is provisional until confirmed by physical testing.

11. What Makes SHIFT NOVA Different?

Most custom shifter knobs focus primarily on appearance.

SHIFT NOVA combines appearance with adaptability.

Instead of choosing a single fixed shape, users can experiment with different grip sizes while keeping the same central shift knob.

Its distinctive approach combines:

• A modular three-size ergonomic system.

• Mechanical interchangeable grip shells.

• A unified futuristic turbine design.

• Customizable tactile surfaces.

• Multiple interchangeable top emblems.

• Calibration components for 3D printing.

• A construction developed with accessible FDM manufacturing in mind.

SHIFT NOVA is designed as an expandable platform rather than a single decorative accessory.

12. Important Development and Compatibility Information

This project is currently a digital CAD prototype.

The design targets the Thrustmaster TH8S Shifter Add-On, but the mounting interface has not yet been validated using Thrustmaster's official adapter geometry.

The current CAD design includes a provisional 11.5 mm mounting bore.

Before functional use, the mounting interface must be checked against the official Thrustmaster design files and revised if necessary.

Digital geometry checks have confirmed that the exported STL meshes are closed.

However, physical printing, snap-fit durability, secure mounting, and support-free printability have not yet been fully validated.

The model should not be considered a verified, ready-to-install TH8S accessory until those checks are completed.

13. The Vision Behind SHIFT NOVA

The idea behind SHIFT NOVA began with a simple question:

Why should every driver use the same fixed grip size?

SHIFT NOVA explores a more adaptable future for sim racing accessories.

A future where customization means more than changing colors.

Where ergonomic preferences can influence the physical shape of the product.

And where 3D printing makes those possibilities accessible.

Our vision is to create a shift knob that combines innovative functionality, modular construction, motorsport-inspired aesthetics, and accessible manufacturing.
