White small plate part

Hey Fabian,

We currently do not sell that part, and a quick online search proved unfruitful. I think that your best bet would be to try and buy an old broken device off of someone (maybe on eBay?) for a cheap price and take the part out of that device to install in yours. It is a rather low-demand part, so buying it individually may be hard. I assure you there are plenty of people that would be willing to sell a broken device, though!

Hope this helps! Let us know how it goes; good luck!
