Lasercut bobbin rack for sewing thread

Here's a quick design I made to store large amounts of sewing thread.

It's designed for 3mm lasercut plywood, and accomodates a variety of bobbin sizes.

Also, this is sized to fit nicely into "Quadrant" 5lt storage tubs (from the Reject shop in Australia), so you can stack a whole bunch, but still keep the dust off.
