Zipper 2 - Complete Zipper Assembly

myminifactory

I've upgraded my old zipper slider design, mainly to give it a sleeker look but also to add extra reinforcement in key areas. I then created the rest of the zipper and printed it at 400% scale. Why did I do that? That's a great question, isn't it. The zipper slider can still be printed on an FDM printer and used as a spare part just like v1. The other parts can also be printed on an FDM machine, but SLA would probably be the better option. I haven't made a full zipper at normal scale and don't plan to. If you do, please post some pictures. Also, when assembling the zipper, avoid using stretchy fabric. I used cotton from a T-shirt, which was very stretchy and made the zipper feel clunky. You're better off using a non-elastic fabric. I don't have complete assembly instructions because I don't know the best way to put it together yet. Still, here's how I did it: I used strands of TPU and ran them through the t-shirt cotton to add structure to the cotton and help keep the zipper teeth aligned. Then, I used a 3D printing pen to glue the teeth in place, one by one. While gluing the pieces in place, I had to stretch the cotton a lot to make sure it wouldn't stretch while the zipper was being zipped. This was the major downside of using cotton: if it isn't tight, then it will stretch while zipping and the zipper will be loose and clunky. All around, it was a bad experience - don't use stretchy fabric. If you have a better idea on how to assemble this, please let me know. Any suggestions are welcome. You can also modify my models as you see fit.
