I quick cover / screen protector / pseudo case I whipped up for the ISDT BG-8S. It is a slip fit and tapers in toward the top of the print for a tight fit so it HAS to be printed in flexible or it won't fit. I printed mine in Sainsmart TPU.
0.2 mm layer height
Thin body, no infill
I used 4 bottom layers and 4 top layers to get no infill. I'm also running a Flexion extruder print head upgrade.
