Magnetic Fly Tray for Velcro - Basic PETG

Needed a small magnetic velcro tray to fit on my waders and/or my sling, that could hold a handful of flies for quick swapping without foam. This is a very basic design that can be modified. The holes are made for 4mmx2mm magnets, but you may need to undersize to 96-97% if you want a press fit. Printed in PETG for sun and moisture resistence.
