USB SD Micro SD Drives Holder (Vase Mode)

Inspired by iomaa's idea, this is my version in Vase mode (Spiralize Outer Contour mode in Cura). This would significantly reduce print time and filament. I slice it in Cura and completed the print within 2 hours and only 14g of filament was used.

Pay attention to the slicer settings below. Those are Cura terms. I have no experience with other slicers.

• Spiralize Outer Contour: enable (required)
• Layer Height: 0.12 (recommended)
• Bottom Layers: >=10 (actual requirement is layer height x bottomed layers >= 1.2, I used 14)
• Line Width: 0.6mm (increase for tighter fitting)
• Flow Rate: add 10% (increase for tighter fitting, my measured flow rate is 92% and I used 100% for this)
• Printing Temperature: 5-10 more than usual to improve layer adhesion, I used 235 for transparent PETG

I always increased flow rate make sure the shell stick to the base in Vase Mode. You may print the test unit to check the fitting first.
