This is a small tray for the IKEA Skadis board that fits a tape measure.
Orient the model so the bottom of the tray touches the print bed then no support needed. Print two of the backing peg. I attached the original Fusion360 model in .f3d and .step format for easy customization.
(I took the idea of the backing peg from another model but unfortunately don't remember which model.)
The author marked this model as their own original creation.
