SILVERCREST Soundbar Stereo 2.1 - for the upper part of the TV

The basic dimensions are in the photos, if you have, for example, a thin TV, you will want to adapt the holder, either by modifying the model or sticking some padding on the finished print (rubbers, etc.)

the holder is probably unnecessarily wide, but I do not recommend going for a smaller thickness such as 70% of the original.

when used without changes, it should be enough to use only 2 pieces (1 on each side), in the case of a smaller thickness, I would recommend placing 3-4 pieces

infill 25-30% minimum
