Just for kicks I 3D printed a speaker design I found on Thingiverse, https://www.thingiverse.com/thing:4750820

I used Fostex Fe103NV's as the drivers and printed the parts with Atomic Extreme Carbon PETG.  I printed them at a fairly high infill of 60%.  This made for a fairly dense cabinet but a very long print, about 90 hours for the body.  They actually sound much better than I thought they would.

So far, I have just printed one speaker, printing the second on now.  I'll post a picture of the cabinet without the side panel when it finishes printing.

Wow, thanks for posting this Debrah.  I never thought about buying a 3D printer before, but these projects are starting to change my mind.  It looks like a great way to build prototypes of any idea you come up with.  Plus it appears a lot more fun to play with than I imagined.

Very cool. Waiting for the 3D printed vacuum tube.

My goodness, you are a busy bee! Between kit building of all sorts, firing off high powered rockets and three D printing of turntables and speakers... the list goes on.
Amazing! Keep it up! Bottlehead forum readers like me enjoy the posts!

Debk, you are an inspiration - I am trolling thingiverse at the moment, looking for speakers to give my dusty 3D printer something to do.

Did you print the sides in a different color of the same material, or was that painted?

Thanks!
The sides were printed in a different color

Hi Debk,

Thank you for the info - that color looks great and an attractive contrast with the black.

Turns out I have a few NOS Radio Shack 40-1197's in my stash...they were rumored, back in the day, to be identical to the FE-103, and thus a bargain-basement knockoff, though the similarities may be just the basket and frame. Good luck for me in any event, since that may mean they'd drop in to the FE-103-sized trim rings, and be a plug-n-play.

I'm printing a trim ring now to check for fit. Thanks again for the inspiration!

  I just ordered a #D printed gear for my lawn tractor. One question that I asked was what actual material is it made from. Turns out to be Nylon 12, whatever that is. Even though you supplied the printing material used, can you describe if it seems to be a softer type of material or harder? And I bet there is a lot of material used in just one cabinet. Overall, I bet that the cost is worth it, but am a bit curious about that as well.
