Futon Sofa Side Table

This is a little side table/organiser designed to fit over the armrests of the Futon Company Cuba type sofa bed. Or any arm rest with a width of 70mm.

To act as a sort of mousepad and for additional grip, the second STL is a 1.5mm thick cover I have printed in 95A TPU which has been superglued to the side table.
Also included, is a DXF of the shape in case there is a preference for laser-cutting/printing and cutting sheet rubber/plastic/wood instead.

For print settings, the table is strongest when printed in the orientation shown. I have run some brief tests and found that 3 external perimeters with a loose grid pattern provides strong internal bracing without requiring more than 800g of filament to print.
