CADing custom mount for car speakers

[earnest vapor]

I'm extremely new to Fusion and CAD software in general. Have used Blender in the past though.
I'm attempting to design a custom mount for aftermarket speakers for my car.
I'd like some assistance in how I'd go about making this model in Autodesk Fusion.

The OEM car speaker is mounted via 3 "ears". Image attached of the OEM car speaker.
This mounting needs to be adapted to the more regular aftermarket circular ring with screw holes around it.
Attached is a sketch I made to try and demonstrate what I want. The aftermarket mounting part needs to be elevated, this is so there is room for the screws to go through and to reduce the Z-depth into the car door.
Because this is mounting literal vibrating parts, it needs to be strong and rigid, so in my sketch, I proposed these 45 degree supports, one on each side of each ear, and around the inner bit.

AI Help

To design a custom mount for aftermarket speakers in Autodesk Fusion 360, you can follow these steps:

1. Import or create a sketch of the OEM car speaker and the aftermarket speaker mount.
2. Create a new design in Fusion 360 and start a new sketch on the XY plane.
3. Use the sketch tools to draw the outline of the mounting adapter based on the sketch you provided.
4. Extrude the sketch to the desired thickness to create the base of the mount.
5. Add 45-degree supports around the ears and inner area for strength and rigidity.
6. Add the necessary holes for screw mounting using the hole tool.
7. Check the design for any interferences and make adjustments as needed.
8. Once you are satisfied with the design, export it for 3D printing.

Feel free to reach out if you need further assistance or encounter any issues during the design process. Good luck with your project!

some sketch like this should be enough, just gotta get the right dimensions

then some extrude and chamfer tool to finish it

as well blue lines = bad, can move in unpredictable ways, dimension/constrain them better

(i might be in dark mode so they might be dark lines in white)

does this help?

[north stump]

gonna be something you design yourself, images dont help much and there is more than 2 measurements to take

[earnest vapor]

this is a scan

i traced round it on paper and scanned it in

[north stump]

you can import it as a canvas for reference, but nothings gonna beat a caliper measurement

[earnest vapor]

I have a caliper too, it's only 150mm one though and these speakers have a diameter of roughly 165mm

[north stump]

that an important dimension other than can clear the hole? could use a ruler and add a bit add clearance

[earnest vapor]

i can do test prints to get dims right its no problem: my main issue is using the CAD software. All I've ever done is extrude a ring sketch. My main questions are:

• how do I model those "ears", the radius of them needs to be exactly right as any bigger it will hit nearby parts in the car.
• how do I make the tube sorta part (see sketch), it goes up on a wall
• how do I add those 45 degree supports

I've got the exact diameters of the aftermarket speaker ring, so it needs a wall on the outer edge down, then those 3 ears, and the supports

[north stump]

ears i would do something like

tube thing?

and if you do the 2 extrudes that touch you can chamfer

(that is 45 degrees, hard to show)

[earnest vapor]

by tube thing i mean those vertical walls that form a sorta tube, do give clearance

[earnest vapor]

so how would I go about making that?

as in, how did you do it

[north stump]

still not clear on the tube part, but the ears 3 circles, each tangent constrained, and dimensioned

[earnest vapor]

this image i found on google helps me explain it.
it's opposite here because the inner part goes back rather than forward and there are 4 ears instead of 3, but this kinda thing

[north stump]

can you draw an arrow or something?

windows snipping tool

like this ear?

[earnest vapor]

this is what i mean by tube

the ears aren't right here, the one on my sketch is what im after

but it gives a general idea of what i'm after

[north stump]

you can make a new sketch off the top round and add more circles to extrude

[earnest vapor]

Genuinely would you be able to do this for me if I PayPaled you or something because I don't think I'm able to do this at my beginner level

[north stump]

id be too much a perfectionist, asking for at least 10 dimensions already, and thats just the base level

CAD isnt that hard, just scarry at the start

[earnest vapor]

Problem is your explanations don't really make sense because you're explaining what to do and not how to do it lmao

if you can make a brik then thats like 80% of your project

rest is making the first sketch match

[earnest vapor]

Here's what I have so far. This ring matches the ring I need to mount the aftermarket speaker to. I have not yet added screw holes.

With the edge that is highlighted, i need to extrude down to make that tube I'm referring to. This can't extrude the whole thickness of the ring, just a few mm wall like 3.5mm. Then connected to the end of that tube, are the ears.

I will watch that video
