Sadly, you should lower your expectations. At this point in time (8/2019), no 3D printer can produce truly 'clear as glass' 100% transparent 3D prints. You can however, achieve translucent 3d prints. Sometimes the terms transparent and translucent seem to be used interchangeably in 3D printing literature, but the two terms are not synonymous.
