I wanted to extend my A8's micro SD card slot up to the top left of my machine. I purchased the following extender (https://www.amazon.com/gp/product/B01D9J8KQE) and built this mount for it. Obviously this was only designed to work with that model but others may work.
This requires supports to print correctly cause of the overhanging parts. I used the built in cura supports and it worked great! Comes with built in supports for better printing.
