What version of scad was used, the newer versions seems to hav trouble with this file

Can someone please help me. I took this file on fusion 360 and sized it to fit an 8” speaker. When I put it on Simplify3D with 15% infill it called for like 8 lbs of filament. Can someone please make a file for me with proper specs for 8” speaker with thinner walls? I’m thinking like 4mm walls. My .8 nozzle with five passes will get me to 4mm and should be strong enough. I tried using the scad for the first time and couldn’t even get it to save in stl. Here is the speaker. https://www.parts-express.com/tang-band-w8-1808-8-neodymium-full-range-driver--264-894

The print should end up over 2 feet tall which is cool. I can do 445mm wide and over 3 feet tall build area. Here is my printer https://reprap.org/forum/read.php?178,793321,793321#msg-793321

Two files would be awesome guys. One with the base not to thick and one without for future modifications. If you want to go crazy another hole on top for a tweeter for two way? : )
Please!!!!!!!!!!!! Haha

Is there any way to force much lower resolution in scad file?

So the most important question, how does it sound?

How difficult would it be to change the mounting hole to fit something like this? http://www.parts-express.com/dayton-audio-rs100-4-4-reference-full-range-driver-4-ohm--295-378

Hi, looks like the driver would be a good fit, should only need to change one line in the openscad file:

hole_cutter(4, 45, 89/2, 4, baffle_length);
changed to
hole_cutter(6, 30, 90/2, 4, baffle_length);

Re-render and then fix the model up with something (The model isn't quite solid, although once it's been sliced you probably wouldn't notice a few mm missing here and there on the outer shell)

The size information of 4" is misleading. When printing this on 1:1 scale, this enclosure fits 80mm = 3.1" speaker, and not 4". More specifically, the inner diameter of the speaker hole (cut-out) is 80mm (3.1") and outer diameter 100mm (4"). I guess some manufacturers use misleading notations, but most 4" speaker are too large for this enclosure.

Diagonal screw distance is around 89mm and vertical/horizontal 64mm.

This design looks awesome, so I had to print it. Will post my make when I find smaller speakers that fit this enclosure...

Yes, sorry, some manufacturers use cone size, some use frame size, I'll update the description.

See http://www.seas.no/index.php?option=com_content&view=article&id=376:h1600-08-fu10rb&catid=53&Itemid=466 for the drivers I'm using for this and the sphere speaker.

Seems quite nice driver.

I realized also some 3.5" 2-way coaxial speakers got perfect cutout diameter for this design. I'll be using Hertz DCX87.3 (although it has only 2 fastening holes which also have to be modified a bit)

I hope there is a parametric design for creating speaker covers.Would give quite nice final touch for the speaker.

I am printing this right now! 16 hours in so far...

Cool, looking forward to seeing how it comes out!

Oh man, that thing is gorgeous! Looks much nicer when printed in that orientation. Well done!
