My Raptor 2 came with a spool holder that mounts up on the 4040 frame - over the print head. I dread the thought of the empty spool, or a spool with a tangle, getting pulled down from the holder and hitting the working parts below.

I designed this pair of attachments to clip onto the 4040 frame on either side of the spool, slide in, and connect to each other. Hopefully, this will prevent a tragic accident should it occur.

I know I could have just put a regular mount up there, but I like the bearings setup that's already there for various reasons.
