Broken link. A ‘LSM6DS3’ search only reports ‘LSM6DS3TR-C’, which is already analyzed (see above).
All the datasheets show the same package drawing, but current drawing pad dimensions are smaller than those defined in the footprint-generator entry data.
With this modification, no chamfer is required, and there are now 0.15mm between pads:
