Anker SoundCore mini holder

English:

I BOUGHT MY SPEAKER A YEAR AGO (2017) I DON'T KNOW IF ITS MEASURES ARE DIFFERENT

This is a holder for the bluetooth speaker SoundCore mini from the brand Anker, it is zip tied to a shelving (44 mm width). I designed the first version about a year ago, I liked it but I wanted to add some features like:
-Holes in the bottom for the bass sounds
-The part of the zip ties was weak so I included it in the back of the holder
-Stylize it
-Add another hole (the one next to the cable holder) to be able to listen to the radio
-Reduce the amount of time needed
-Make it easier to take out the speaker
-Cover less the speaker because it has a nice design (also reduces the amount of filament needed to print it)
-The place for the cable is now an oval instead of a circle and a little bigger.

I also posted the old version, if someone has an idea of how could I improve the design please leave it in a comment!
