Ultimate Snap-Fit Articulated Flexi Keychain

I’ve heard you! Introducing the all-new Ultimate Snap-Fit Articulated Flexi Keychain. 

Now featuring a ball-jointed, snap-fit link system with 360° chamfers for seamless flexibility and style.

Users have been asking for longer versions of my original articulated keychain. Rather than just offering extended versions, I decided to provide individual links that can be printed separately - allowing you to customize the keychain to any length you want.

I also received feedback suggesting more chamfers on the bottom for a more uniform design. So, I’ve added them!

Now, you can get even more creative by printing the keychain in alternating colors to make it truly unique.

What you get in summary:

• Ball-jointed, snap-fit link system for smooth articulation

• 360° chamfers for enhanced flexibility and a sleek look

• New angled link design

• Customize the length by printing as many links as you need

• Create unique designs with alternating zebra-style colors

Print settings

0.2mm layer height works well with 2 perimeters and 15% Rectilinear infill pattern. 

Important Notice: Please avoid using an infill greater than 15%, as exceeding this may make it difficult for the links to snap together properly. For the best results, I recommend using Silky PLA. If you experience difficulty snapping the links together, you can gently file down the ball joints to improve the fit.

Remove the parts after the print sheet has cooled, then flex the sheet to release it.

For the best results, print the links separately and snap them together afterward. (This is a great opportunity to use Sequential Printing, found under “Output Options” in PrusaSlicer.)

Important: Sequential Printing may not work correctly if you’re using instancing for the links. Be sure to check for any errors after slicing and ensure the extruder won’t collide with printed parts. UPDATE: Looks like this has been fixed in PrusaSlicer 2.9.2-rc1

I have also provided a print-in-place full length version for your convenience.

Tip: Avoid repeatedly snapping the links together and apart, as this can cause gradual wear on the joints over time. 

Enjoy!
