This case holds a Zoom H2n recorder and some accessories (on the right part): typically an USB cable, spare batteries, a small powerbank, some SD cards… Note that powering the H2n from an USB powerbank removes the need for batteries.
The *_PLA parts are meant to be printed in some hard material like PLA or PETG. The *_TPU parts can be printed in hard plastic (the recorder fits) but give better protection if printed in flex material. I used PLA and 85A TPU.
The TPU part 1 goes in the left side of the case case, parts 2 and 3 can be glued in the cover recessed area using double sided tape.
