There are of course 3d print options available like this one on thingiverse but you'll also need to source and buy a harness and fix it altogether. What drew me to the unit I've review here is the low cost and fact that everything I need comes in one package. More importantly it works like it's meant to. You will need to be very careful with aligning pins but if you can manage that, this is a low cost and simple solution.
This unit is available exclusively from Banggood so far as I can tell. Please comment if you know any ready made alternatives available worldwide and I'll link here too.
