Description
I designed these parts to go on my custom built LM386 based guitar amp.
I got the Wood Box from Michaels -- there are some like it on Amazon.

The Speaker Grills are designed for 3 inch speakers. They have fit several different brand 3 inch speakers that I have so it seems to be quite standard hole pattern for that size.
Bass Tube -- to give the box a speaker vent and allows the speaker to move. Actually makes it sound way better.
The Box Feet -- these I printed in TPU for rubber feet.
There are some round O-Ring grommets that go between the speaker grill and wood cabinet -- this prevents vibration from the grill and the cabinet. These are also printed in TPU.
Knobs -- these are standard 6mm hole knobs for the B10k potentiometer that I used.
