This is an attachment holder for the Shark FlexStyle hard-sided case. My wife was tired of the attachments sitting in the square section of the organizer loosely and falling out when she went to open or close the case.

This solves that problem by giving the attachments something to hold onto while staying secure in that section of the case.

I recommend printing the file upright with the smaller side on the plate with the attachment circles facing facing up. You can print with the larger side on the plate, but you will need supports on the circular sections.
