Those mounts turned out fantastic!

I really wanted this excavator to have proper sound. Deep and powerful bass. Not toy-like. I looked around a bit to try and find a large speaker that would fit, but came up empty. So I printed one instead. My biggest print to date. 21 hours and 290 grams of ABS. :-) (25% infill)

The speaker driver is this one:
- Pioneer TS-G1045R 4-Inch 210 W 2-Way

On the back there is a speaker terminal that I bought on Ebay:
- 44.8x21mm 2pin Red and Black Push Type Speaker Terminal

And then there are four self-tapping screws in the front, two on the terminal, and three that fasten the speaker box to the base plate.




I cut off the mounting tabs on the speaker driver, because I needed the screw holes to be closer to the cone. The flange on the self-tapping screws is now what holds the speaker driver in place:




Soldered the wires that came with the speaker to the terminal:






Attaching the speaker box to the base plate with three self-tapping screws. I added a soda can too, as I've seen a few others do that lately. My build is dwarfed by DADSGARAGE's and Cooper's though, but still it's not that small. :-)

Great job with all of the 3D printing, it's very fun to see what people can come up with and easily create. If the sound doesn't seem quite correct with your setup, put some insulation inside of the box like bed top foam or something like that.

Hi Trucker_Jo!

Yes, it's pretty cool, but this print was a pain. I started it and it ran for 5-8 hours four times before I got one successful print. The problems were lifting edges, support coming loose, support lifting and SD card error. :-)

I'm definitely going to add some dampening material inside. Initially, I tried to print something like that, but it didn't work that well, and I decided to do it the traditional way, and then completely forgot about it. Thanks for reminding me! :-)

Here are some images of my attempts at printing the inner dampening:

Interesting, thanks for showing us the details!
