HSW Hot Wheels System – Mainline Topper Pack

Overview

Customize your HSW Hot Wheels Mainline Display System with six interchangeable themed topper modules.

The Mainline Topper Pack adds different visual styles to the same modular rail system, allowing you to match the display to specific collections, series or personal preferences without changing the underlying display structure.

Each topper uses the same mounting interface and can be swapped independently.

Included Topper Modules

The pack includes 6 different designs:

• Batman

• JDM

• Car Culture

• Racing

• TH

• STH

Additional topper designs may be added in future updates.

System Compatibility

The topper modules are designed for the standard Mainline configuration of the HSW Hot Wheels Display System.

Required base system:

• HSW Hot Wheels System – Mainline Display

Compatible with both:

• Direct wall-mounted Mainline displays

• HSW-mounted Mainline displays

The HSW mounting adapter is already included with the Mainline Display System.

These toppers are not compatible with the wider Premium connector configuration.

For wider Hot Wheels Premium blister packs, use the Premium Display Upgrade.

Interchangeable Topper System

All six modules use the same mounting concept, allowing the topper to be changed without rebuilding the complete display.

This makes it possible to customize individual display sections for different collection themes or change the appearance later as your collection evolves.

Multicolor Printing

The topper designs are especially suited for multicolor printing.

They can be printed using:

• AMS / MMU systems

• Manual filament changes

• Other multicolor workflows

Contrasting colors help emphasize the raised graphical elements and make the individual designs stand out.

Mounting

The topper modules use M3 countersunk / flat-head screws for a clean installation.

• Screw type: M3 countersunk

• Recommended length: 8–12 mm depending on the mounting configuration

Printing Recommendations

• Material: PLA or PETG

• Layer height: 0.20 mm

• Infill: 15–25%

• Supports: Not required

• Orientation: Print flat for best surface quality

• Multicolor: Recommended

PLA is a good choice when clean details and multicolor surface quality are the priority.

Use Case

Ideal for collectors who want to organize their Mainline display around different themes or collections.

Use different toppers for JDM cars, Treasure Hunts, Super Treasure Hunts, racing models or themed collections while keeping the same modular display structure.

Notes
