Has anyone ever 3D printed replacement blanks for the dash buttons that aren't in use?

Looking to install some USB sockets - ideally next to the cigarette lighter as the electrics will be accessible but would prefer to print a new blank rather than butcher the original.

You can buy blanks as well as a dual usb unit from places like aliexpress

 

Something like this (cheaper options are available) 

I just found this on AliExpress: 
 Alphard Vellfire Interior Accessories

There are two different sizes for the usbs to fit toyotas, you need the short fat ones. Ebay and Amazon also do them. Best on I got was one to fit next to the 12v socket below the gear shift. You just unplug the cable from the 12v socket, then daisy chain it. No other connections needed.
