I liked the shortened and curved Filler remix, but it still had a completely unnecessary 15mm sticking out for the rolls that I use, which limited my access to things behind it... so I chopped it down even further.

It'll now be a real tight fit on your standard spools from eSUN etc (I assume, I have yet to print it), but, will still hold them.

Due to decreased leverage, I believe it is even stronger than other versions.

For brackets, see the original item or any remix that suits your needs.
