Some tweaking might be required especially for the power board for battery charging.
I have not tested the 3d printable "wood" pieces as i made the 10mm x 90mm x 8mm from plywood and glued them in place.
I recommend putting the seam for the outside shell on the bottom of the shell where the feet go so it will be hidden
A (rough) list of parts i used along with the 3d print
PAM8403 mini amp
VHM-314 bluetooth board
1.5 inch speaker (hard to know exact model as i have 2 similar ones but they are slightly different size
KCD11-101 switch
Power board from a small powerbank (also don't know specific model as i took down a random powerbank i had laying around)
AA battery terminals
USB thing you can solder wires to and get power from the power board (i don't know the name for the part)
Glue to keep everything in place :D
The model is not perfect as i am just a beginner but still wanted to share this if someone is interested
The author remixed this model.
The sound chamber is from the original model but i added a place for electronics, wood accents and a outside shell
