This is a replacement zip toggle designed to easily connect to any medium to large zip loops where the metal/plastic toggle has broken off.

Often when this happens, the gap to slot something into the hole is tiny or non-existent so this design allows you to connect a toggle to a completely enclosed loop using a simple locking mechanism.

[This is still a thing in progress. It is absolutely a fully functional design in it's current state but I'm still working on improving the aesthetics, the grip, and the clip design to allow maximum movement on the zip]

I hope you enjoy printing and using my design. To help me keep designing and uploading more things, as well as continue to run my YouTube channel (www.youtube.com/c/3drevolution), please consider making a small donation to me via PayPal: www.paypal.me/JoshForwood
Thank you!

For maximum strength, these should be printed in the orientation they are currently set to, lying on their largest flattest sides.

However, if your printer can't bridge the gap on the case part in that orientation, then you can rotate it 90 degrees so it sits on it's long thin side. There will still be bridging required but a much shorter distance.

Due to the fine detail in the clip lock mechanism, a fine resolution is recommended for this, I've printed at 1 micron later height.

With regards to infill, this part may be put under quite a lot of strain so a minimum of 50% infill is recommended but ideally more around 80%.


Slot the clip piece through the ring you'd like the toggle to be attached to

Align the case opening at the end of the clip so the clip is pointing down the length of the case. Push hard ensuring both pieces are kept straight until the clip locks into the case.

Pull the clip and case apart to reveal the full length of the clip.

You now have a fully functional zip toggle

Thanks a lot for sharing this useful thing!

Glad it's helpful!

Hi, I've printed this, and works fine at first, but soon the clip starts coming out by itself. Any idea how to fix? I've printed 200 micron, will try at 100.

I scaled this to 80% and it worked pretty well for my backpack zipper.

Just want to say that people still appreciate that you posted this! I just fixed the zipper on my winter coat, with your Zip Toggle. Worked perfectly! Thank you.

Hey StumpHunter, thanks for posting! That's really nice to hear that it's helping so many people. I am quite surprised that it's been so popular so am working on a revised version which I'd imagine I'll upload some time next week.

That's awesome. I printed some but to fit my backpack I had to scale them down to 70%. It was tricky getting the lock mechanism to work as it was a tight squeeze. But I got them in and the seem to work just fine. Thanks. Looking forward to the revised version.

Yeah, to be honest it was designed for a very heavy duty zip so is overkill at it's native size for most things.
The revised version will be more multi-purpose, easier to print and more comfortable to use :)

Hey, I LOVE this - any chance you could share your original file? I'd like to customize this with my name and perhaps some ribbing for grip or maybe a half circle raised at the far end for grip.. probably like to do away with the hole at the end as well... Anyway, I'd love to play with this if you wouldn't mind.. thanks for uploading!

Hey donquixote, sorry for the late reply. I'm working on a revised version which I'll post later this coming week which hopefully should meet your requirements, let me know what you think
