This is my remix of LarnOm's great Ender 3 bed handle made for my new CR-10S (should fit Cr-10?). Anyway, it fits my 310mm x 310mm standard bed.
I used Microsoft 3D builder to split the original file and then extended the middle part.
Print however you like but it will need supports down to the bed for the middle part.
Please leave a comment if you like this, or not. :-)
