Here’s a black version I found that says it’s for the 1000 but I can’t be certain.

It’s this one that i modified using mounting tape and by cutting out a wider charger port hole. I also plan on cutting out another hole for the SIM card slot which is used for my psvsd sd card extension now. https://www.amazon.com/dp/B07KS1FY9G/ref=cm_sw_r_cp_api_i_XJQQ02HXENRRW1MQ60TF

The brand is Top Player I bet you could find one cheaper on eBay or another site. One last thing, top player makes a carrying case for the vita triggers that I highly recommend as well
