This stand has cutouts for pogo pins (small cobber pins with build in springs) that connect to the 4 small, round cobber plates in the bottom of the tablet.
On the pictures you can see i used some double sided tape to fasten the mount to the table. This is just to keep it from sliding around when i insert the tablet. its not needed.
When facing the tablet screen, the left pad is +5v and the right most is ground. I just used an old usb cable and cut the one end off, and then soldered the wires to 2 pogo pins. Then used a glue gun on the bottom of the pins to act as isolation and protection.
Its not fast charging, actually its pretty slow charging, but its enough for me.
print on the side. Use pla :)
