Nintendo DS tend to break their right plastic eyelets. I propose a replacement part to fix this.
You have to dismantle the device to access to the eyelet, cut what remains and glue the replacement part.
It is not perfect, it is not aesthetic, but it does the job.
I use PETG and 0,2 nozzle because of small details and tight tolerance.
I got a bunch of broken NDS and i found two types of broken eyelets. I propose both parts: just choose the according plate.
