Speaker Tube

I was inspired to create this thing when I noticed that PartsExpress had a number of TV speakers in their buyout section (Jan 2018). I already had two from an older TV so I created this speaker tube thing for my wife to listen to podcasts. I wanted it to be easy to print and assemble, requiring only some cheap ebay parts and 8 screws for the speakers.

The total project probably weighs in at 250g. You may have noticed the classy white on off-white appearance in one of the pictures, this is due to me running out of my original white and using a another spool from a different manufacturer.
