Roland FP-30X table top tablet stands

The curved shape of the FP30-X piano top does not allow to place any item steadily. These stands, glued to a wooden board will attach securely to the piano, providing a flat surface. 
 

Printed on a Prusa MK4 with PLA in draft mode, I then used neoprene glue to assemble the stands to a wooden board 950mm X 240mm - 8mm thick. 

The main challenge was to adjust the position of the points of contact with the piano so the stand is steady with only 2 points of contact with the curve of top of the piano. You will find 3mf and original FreeCAD file (very dirty) to ease your derivative work.
