New design

[LC Ghost]

So after hating the usual speaker mount options for the FJ40 I decided to build my own.
I wanted the housing to be able to take a 6.5 in speaker instead of the 5.5' that were in my 40. The 5.5's were not enclosed and were mounted to the back tub wall.
I made a prototype in cardboard then drew it in Fusion 360. The new design has feet so it will sit above the ridges in the bottom of the tub and sit over the nut for the roll bar mount.
A 10mm bolt drilled through the box holds it in place into an existing threaded hole on the back wall.
The angle is so the drivers side speaker faces the passenger and the passenger side speaker faces the driver instead of facing the jump seats.
I also designed an air vent for the speaker to allow better movement of the speaker cone. I also put poly fill in the speaker boxes.
I know the color is not a perfect match but I think it works. Let me know what you think.

Awesome. So which model printer? What filament? How long did it take to print both?

The printer is a Creality K1C. I used Creality Hyper PLA filament in Golden /Yellow. Due to the supports on the inside of the box it takes about 1 1/4 rolls per box and each box takes about 23 hours.

Thank you. They look wonderful to me. Nice design IMHO. I haven't got into 3d printing yet but I watch a lot of vids. I want to do some "lost PLA" casting to make replacement parts and maybe jewelry.

Do you think the PLA will hold up to the sun/ozone?

I think there is a place somewhere around here where you could put the file so others could print their own.

Nice! I put my speakers in a similar spot, but made the enclosure from mdf which got sprayed with bedliner. I'm a cabinet maker, so it's my easiest medium to work in.

Here is a good article on the differences between filaments...

When you get old like me you can get hearing aids that send your iTunes directly in your ear. But you might find $4250 kind of expensive for a speaker system.

Curious how the sound quality is between 3D printed versus mdf?
I believe the holes at back corners are for the FST bows. Should be either two or four holes on the wheel well below that depending on the year for bracket to hold the bow in place. If vibration is an issue that might help. If like bass and want music heard in a moving 40 vibration could be a problem.

Those are cool, nice job.

Depends how he printed them as far as wall thickness and density goes. Mine sound decent, but I'm sure it could be improved. MDF is a pretty typical material to make enclosures out of. Doesn't resonate easily and keeps the energy from the speaker doing what it is supposed to.
