Khung Cockpit cho thiết bị Bigme B6

Print the frame in PETG and the button in TPU or PETG.

The frame model already comes with a brim because I had problems with the slicer brim ripping off the print on my A1 mini.
Use a cutter to remove it from the print.

Use a 3cm piece of TPU with one end melted and loop it through the two holes to secure the reader.

The hole for the USB is cleaner if you enforce supports on that part.

I designed the USB hole so it fits the plug of my Anker power bank but multiple cables with smaller plugs that I tried worked.
