APA102 addressable rigid bar

This is a new custom product from one of our client,they done 10led/pcs with Molex connectors

(2.54 pixel pitch) before,but now they ask to do 12led per pcs.
This one we use APA102 led chip,not SK9822,and the size is 435*14mm,
there has 4pcs*5mm diameter holes for you to install that,both end with 2pcs*4pin Wafer curved 

needle connetor,but the pixel pitch(connector) just has 2mm.
If you have any new idea,pls let us know freely.
