RUIZU D29 Case

Case for RUIZU D29 Mp3 media player.No cases found so I ended up designing my own to fit.Printed with a random soft TPU I had lying around, so unsure what type it was.Needs to be a fairly soft TPU to fit, as I tried a firmer TPU but had to cut the case to take it off.Ports for headphone cable and charging port as well as hole for mic and slot for rear speaker.
