Just a simple handy SD card keychain ;)
 

The larger part is designed for a snug fit, ensuring it stays securely attached to your keys.

The card is recessed by 2mm, so it fits perfectly into any SD card slot without issues.

Print tips:

• Use a standard 0.2 mm layer height with 0.4mm nozzle.
   
• Apply a small drop of glue to the lower part. 
   

Tell me in the comments if you have any tips or recomendations. :) 

Thanks for checking my model ;)
