Adding the drawings for the respective optical disks below for reference:

PWB_ENCODER_OPTICAL_DISK_005

source reference issues:

Regarding the mass properties, we keep the material as PVC for these components. We will still measure the physical disks and verify the mass as and when we have them.

divyashah commented 7 months ago

Since the disks are very thin, it is difficult to get exact measurements. The weight from CAD, keeping the material as PVC are as follows:

PWB_ENCODER_OPTICAL_DISK_005	PWB_ENCODER_OPTICAL_DISK_006

Mass = 0.108 g	Mass = 0.084 g

In that case, we can close this issue.
