8x5 base with surround to fit in Bisley a4 style paper draws.

The draw height is approx. 49mm so you can have up to 6u height of Gridfinity bins

I cut this out of 3.2mm MDF and it works great. The wood will flex enough to put the base under the lips each side of the draw.

The bins are on the right hand side, so you can use the extra space in the draw , and if you want them on the left then turn it upside down!

Included are a dxf and Lightburn file

I found this recentley and it would have made the process easier... may help someone
