Not that I've seen but I can try to describe it.
You should have a thin large I ring and a thick large o ring.
Put the thick one inside the top cap.
Put the thin one over the base threads and slide it to the bottom.
You should have a ceramic. Put this inside the threaded ceramic holder.
There should be a centre post. Put the small solid plastic ring over the threaded section and slide to the plate.
Put the post, threaded side, through the hole in the ceramic holder. Put the locking but inside the ceramic. tighten.
Put the bottom circular knurled nut onto the other side of the centre pin. This may be tight. Use Vaseline or sumat.
put the remaining rubber o ring on the bottom of the centre pin, after the knurled nut.
when a coil has been made, insert the atomiser section into the base, be careful not to cross thread and tighten the larger knurled ring around the ceramic holder towards the base.
Put the mouthpiece on next. Then the body and finally the top cap.
