I'm new to 3D printing with my A1 Mini. I created this model using Blender from scratch as I wanted to learn building 3D models too of my own designs. This NFC keychain tag's my first self-built model. It has a Pause included to give you prompt and time to put in your 25 mm NFC tag. No design at the back.

Specs for the images shown: 

Printer: A1 Mini 0.4 Nozzle

Filaments: 

Bambu PLA Onyx Sparkle Black

eSun ePLA Milky White

Process: 0.20mm Standard @BBL A1M

Let me know how this works for you! Thank you.
