Gridfinity Cutting Board Drying Rack

I wanted to create a drying rack using Gridfinity, so I created this rack to stand my cutting boards for drying after washing. Fits 20mm and less boards. Printed in PETG, but PLA or any other filament should work as well. Printed without supports and without brim. Sized to fit 4x2 gridfinity blocks. Added some holes at the bottom to allow water to drain.
