This model is a modification of the protection found at THINGIVERSE: https://www.thingiverse.com/thing:4899874 to be able to attach the JBL FLIP 5 speaker: https://www.jbl.es/outlet/JBL+FLIP+5-.html

It can be printed in PETG with many walls and padding and with the orientation shown in the images. In TPU is much more recommended as it will be a much more impact resistant piece and will not break.

There are several versions, I recommend printing the versions that have holes to use a bungee cord and especially the version that consists of two pieces joined by a rail.

It can be printed in PETG but it is advisable to print it as shown in the image of the cure program so that the part has strength and bending capacity and does not split.
