ESRack - Pure Resonance Audio SMG1 Mount (Remix)

This is a functional remix of the ESRack - Front Plate by EvilProphet.

I needed a reliable way to mount a Pure Resonance Audio SMG1 Sound Masking Generator into an ESRack system. This customized front plate provides a perfect, secure fit while keeping all vital rear ports and front-facing controls fully accessible.

Design Features

• Perfect Alignment: The base platform includes a custom bottom notch cutout. When the SMG1 is placed on the shelf, this notch perfectly aligns the front-facing controls (Tone, Gain, and Power Switch) with the display window on the front plate.

• Reinforced Mounting Blocks: To ensure a robust, long-lasting installation, I integrated solid modifier blocks into the slicer project file. These modifiers allow you to drill and tap reliable threads directly into the print.

• Rear Access: The design leaves the rear area open, ensuring easy access to the RCA Audio Out, Aux Out, and DC Power Input jacks.

Printing & Slicer Setup

These settings were tested on a Creality K1 Max to provide excellent structural strength and functional precision:

• Printer: Creality K1 Max

• Material: PETG (highly recommended for functional strength and heat resistance)

• Wall Loops: 3 loops (perimeters)

• Infill: 15% Gyroid infill

• Supports: Optional. Using supports is recommended if you want to ensure the connecting tabs/holes remain perfectly round and uniform.

• Orientation: Print face-down for the cleanest front-surface finish.

Adding Reinforced Mounting Zones

To make the mounting plate strong enough to handle screws, you will want to reinforce the areas where the mounting holes are located.

You should add vertical modifier volumes in your slicer over the screw-mounting paths:

• Infill Modifier Suggestion: Set these modifier zones to 100% infill or a high number of perimeters (walls). This ensures that when you drill and tap the holes, you are threading into solid plastic rather than hollow infill space.

Assembly Instructions

1. Insert & Mark: Slide the SMG1 onto the shelf from the rear and push it forward until the front control panel settles into the front window cutout. Mark the four mounting hole locations through the side flanges of the SMG1 onto the reinforced zones of the shelf.

2. Remove the Unit: Slide the SMG1 back out of the mount to keep it clear of the workspace.

3. Drill & Tap: Drill pilot holes at your marked marks and use a 6-32 tap to thread the holes.

4. Secure & Install: Place the SMG1 back onto the shelf, align it with your newly tapped holes, and secure it using four 6-32 x 1/2" screws. Once assembled, slide the complete unit into your ESRack setup.

Hardware Needed

• Screws: 4x 6-32 x 1/2" machine screws

• Tools: Drill bit and 6-32 tap
