At customflashdrive.co.uk we have launched a 3d print your own section, where you can download the stl files for a couple of euros. Still I am trying to share some stl files of these name flash drives here and there for free.
Step 1: Set Up Your 3D Printer
I recommend the following cura settings:
layer height / resolution: 0.2 mm
wall thickness: 0.8 mm
no support is needed
Here in the stl file, which is already repaired, there is an extra key ring. So it is slightly different.
