Unfortunately the original piece from my valk snapped, the piece was great and fit perfectly.

it fits just well

SInce someone lost a piece for my cube it fitted perfectly.

Works well with the other parts of my cube

I decided to try and do a quick mod with a sticker-less Valk 3 - change white for black - all you need is a couple of spare black edge pieces, a couple of spare black corner pieces, a centre piece and centre cap and you have a new colour scheme :-) It took me all of 10 minutes including filming the clips! Next phase will be some magnets, probably N45's...
