I've had a couple of this style of plastic clip crack. Wrapping it in thread and then applying super glue seems to work pretty well. I also tried wrapping with fishing line, but it came undone pretty quickly. Just wanted to share the tip! Now if only I had a fix for when the prongs on the other half break off.
I've not used a Dremel - are you clamping the filament end-on, kind of like a pencil lead? Would a drill potentially work in the same way, if so, if you can align it in the chuck properly?
Clamping? It's got a tip that you screw down around like the chuck of a standard drill. Dremmels spin at high speeds, 7000-15,000 (or more) RPM. The tip uses a small wrench to tighten down.
You stick filament into the tip. It spins at high speed. The filament heats up from the friction when you touch it to an object. It then starts to melt and bond with the object.
Thanks!
