Custom Speaker Stands
We acknowledge Aboriginal and Torres Strait Islander peoples and their continuing connection to land and as custodians of stories for millennia. We respectfully acknowledge the land on which we all meet today, and pay our respects to elders past, present and emerging.
In this series of two workshops you’ll work with our resident audio expert to customize and build our in-house speaker stand design. Your design will be cut by the Applied Creativity team between workshops one and two so you'll have a single sheet ready for assembly.
Workshop one covers:
- introduction to The Edge Recording Studio and Fabrication Lab
- Customising a a parametric model in Fusion360, then exporting files to cut
- Layout of cut files in Vectric Vcarve
- Demonstration cut of files
Workshop Two covers
- Use of hand tools to prepare CNC sheet for assembly
- Assembly and finish of speaker stands.
- Basic Fusion360 parametric modelling
- Basic Vcarve layout for CNC
- Basic hand tool use

Workshop Walk through
Introduction to The Edge
- Fabrication Lab
- Recording Studio
Step Zero: Before we Start
Turn on your Fabrication Lab laptop, log in as 'edgeuser' with the password 'edgeuser' and open Fusion 360.
Step One: Fusion 360
- Open Fusion 360.
- Click File and save.
Make a Component
In the tool bar click Assemble then Make a component.
- An assembly is an organisation of parts (components).
- Multiple assemblies can be joined together to make a whole product.
Making a Sketch
Select the rectangle tool
then choose a plane to draw on,
and draw a rectangle.
Once the rectangle is complete, it is filled in with a solid colour to indicate it is 'sealed'
Playing With Constraints and Parameters
Constraints are geometric properties that can be used to control your sketch. For a comprehensive explanation check out the wikipedia page.
Then change some parameters, and try to move your shape.
Then click stop sketch when you are done.
Now that you have done some exploring in Fusion, go to file and open a new design for a fresh start.
Measure Your Speakers
Go online and find your speakers and grab the length, width and height.
In your new design click parameters in the tool bar (it can sometimes be under Modify). When the window appears click the little green plus to enter new information.
Then making sure the measurements are set to mm enter the length, width and depth of your speaker into the table one by one. At the end select all the stars to make them all favourites.
Sketching your Speaker
Begin drawing the rectangle from the origin. Before clicking to creating the rectangle two measurement boxes appear.
In the width box write width and click enter.
Then click tab which will take you to the length box.
In this box type length then click enter and then enter again.
Check that the rectangle cannot move then once done click stop sketch.
Click the rectangle the click create then extrude. A window will come up to the right. In the box next to distance type depth(or whatever you named your speaker depth in parameters). A selection box asking if you want to assign the parameter depth will appear. Click on it then click ok.
The Edge Speaker Stand Model
View the Model online
Download the Model or open in Fusion360
Step Through Design History
enter your measurements in the parameter window:
- one at a time (best practice)
- Changes are applied immediately
- Click OK to apply
- Use undo to revert (after closing parameter window)
Using VCarve Makerspace Client Edition
It is imported to use The Edge makerspace ID - otherwise your designs will not open on the Fabrication Lab machines! To do this open the about menu
And enter The Edge Makerspace ID.
You will then have to close and relaunch VCarve.
Create a new Vcarve File
2. Choose Either a Single Sided Job or Double Sided Job in the Job Type (double sided jobs are ones that you need to turn the material over to make cuts on the other side)
3.The standard Job Sizes are 1200 Width(X) 1200 Height(Y) Thick 15 (Z).Ensuring you are using the mm option as your unit of measure.
Import your vector File by selecting the Import Vector icon in the File Operations Toolbar or select Import Vectors from the File Menu. Use the DXFs we exported earlier from Fusion 360 or these examples.
Vcarve will import your vector to the bottom left corner of the Design Window ( zoom out if you can't see it )
Now ensure that all the paths that make up the shapes of your job are closed/ joined. Select the Join icon from the Edit Tools Toolbar and select all the paths you want in a shape.
You may need to adjust the tolerance of the Join tool to ensure Vcarve can fill in the gaps between the multiple paths.
Tool fit and Assembly
For this example job we are using an 6.25mm tool, so lets take a moment to measure our designs tight sections to make sure the tool will fit. otherwise we may produce a piece that looks like this.
We will use the measuring tool.
Clicking on one edge, then the next, this section of the Fretwork is about 4.5mm wide. Too narrow for our (6.25mm) tool.
Lets widen that gap using our node edit mode. Click on our curve to select it.
Then drag and grab the points you want (they will go red) , then move them with the mouse - our nudge with the arrow keys.
In order for our design to fit together straight of the machine - you may need to use dogbone fillets. This is a small arc on inside corners that fits the tool, and ensure a joint fits to its full length.
Then hover over an internal corner (you may have to ungroup your shapes first) until the cursor turns into a tick.
Its time to move and arrange our design on the material - the first step is to group all the shapes so we don't lose our design. Use ctrl-a or drag and select everything, the use Ctrl-g to group (or the group menu button).
Group and Move
In the 2D View tab, select the Transform Mode selection tool form the Edit Objects Toolbar and drag the shapes into place on the rendering of your material. Or slow click on your shapes.
3. Once you are happy with the placement of the individual parts on the material, ensure that you do not have hidden / multiple copies of the paths that make up the shapes. Search for these extraneous paths by dragging or deleting ungrouped paths and undoing the operation when you have established you only have the paths required.
Setting up Toolpaths
Toolpaths are the path or route the CNC Router will move the spindle on. The path always follows a vector from your file.
The CNC Router requires more information about the type of tool you are using and how you want to cut/remove material. this is defined in the toolpath menus - found in the top right.
The Edge Vcarve Tool Database
Please use the latest version of The Edge Vcarve tool library. Download, unzip, then merge this into your version of Vcarve
1. Select a shape you want to apply a toolpath to.
2. Pin open the Toolpath Toolbars
3. Check the values in the Material Settings
4. Select one of the 12 types of Tool Operation you would like to apply to the toolpath - in this case
Remember to select the Tool operation order to optimize cut accuracy and minimize the effects of vacuum bed dropoff as parts toolpaths remove material. As a general rule use the following order:
- Drill and engraves and surface level pockets first
- Then cut through pockets, internal cut paths and large parts
- cut external paths small parts last.
Offset and Layout your cutting job
Once you are satisfied that all the required Paths are closed shapes you can layout the multiples parts required to be cut (Eg a 4 legs per stool and 6 stools are to be cut)
