How to Repair Broken Plastic Parts (Broken Bottle Cap)

Part of the reason for why I haven't made an Instructable for so long is because I've been working on a REALLY big project right now.

The other part is trying to find out how my water bottle found out about the upcoming Fix-it! contest, and decided to break. I came up with a fairly simple way for repairing it, so in this Instructable, I'll show you how it was done.

To do this, you'll need a Hot Glue gun, some galvanized steel wire, a drill with a small drill-bit, a file, and wire cutters. Needle-nose pliers might also help.

Let's get started!

I used a file to rougher up the surface, since this helps the hot glue adhere better. The more, the better.

I drilled a hole in each side of the cap. I recommend using a drill-bit that's slightly bigger than the wire that you chose

I wrapped the galvanized steel wire around the cap. I think using more thinner wire would be stronger, but this doesn't have to be very strong. I cut off the excess with wire cutters, and moved on to the next step. If the wire that you chose was really tough, you might need to use pliers...

I poured tons of hot glue onto the cap. Add only a bit every time, and it might take the glue a few minutes to cool off, so be careful!

Done!

Now, If you'd like, you can shape it in with your hand (while the glue is still warm, it feels a bit like putty), cut off the excess with a knife, and give it a "polished" look with a lighter. Good luck! :)
