Hinge-less Filament joiner splicer fuser tool

Hingeless version is now as good as I can get it. It seems to print a little differently every time, so I can't vouch for other printers, but my Snapmaker seems to have the right balance of clamp grip-to-gap that keeps the clamps tight, but doesn't fuse completely during printing.
