Help - Can't figure out way to connect spool to webbing

[Sperkowsky]

Hello, so our team is working on our off-season bot right now. Originally the design called for a pvc spool but it was switched to a 3d printed one because of sourcing problems.

When we were running the elevator up with a battery it stopped 3/4 of the way up. After closer examination it is from the shaft key literally tearing into the plastic.

We then found a metal spool that fit the shaft perfectly. The one for belts on the Kop drive trains. But, we can't figure out a way with our limited manufacturing abilities to attach the webbing to the spool.

Here are some pics

The webbing is just there for pictures. It's only ziptied up there.

Thanks
