Strong Keychains with NFC Pocket - 70+icons

!!!!!!Please read carefully before printing!!!!!!

Hi everyone!
This is my simple but tough keychain design packed with lots of patterns and a nice internal pocket perfectly sized for an 25mm NFC chip / tag.

I don't offer flashy rainbow multicolour prints – I focus on clean, strong logos/text that look cool and last forever. (recommended from petg)

-Halved Snap together sides optimised for mass printing

-The chain hole strong and big enough for use direct on the ring

-70+logos and icons and coming more

-3 Big Group : Social Media and Apps, Jobs and another icons, Car brands

-One short tutorial for midlayer pause for NoAms

And the best part: you can now achieve almost AMS-quality two-tone results even without an AMS!

How it works (very easy mid-layer filament swap without AMS):

-Slice the model in Bambu Studio using your preferred settings.
-Use two filaments/colors:

 ˙--Filament 1 = body/main color 
  --Filament 2 = logo color (the one you want to appear in the first layer)

-Important – add the pause command (this is the trick):
    Go to Filament tab →

- select Filament 2 (the starting/logo filament) →

- click the settings/gear icon to edit it.
-Go to the Advanced tab.
At the very end of the Filament end G-code box, add this line:  

M400 U1 

Bambu Studio will place the M400 U1 pause command exactly where it would normally do an AMS filament swap

 — that is, right after the logo part finishes printing and before the body color continues.
When the printer reaches that point: 

- It will pause automatically  
-You manually unload the first filament  
-Load the second filament (Body color)  
-Press Resume on the printer screen
→ The print continues with the body color without needing any AMS!

Result: a super strong, permanently embedded logo in the keychain body – no gluing for the logos. Looks clean and pro from both sides.

Enjoy printing!
