Save the environment! If you happen to print the Sine Wave Lamp Shade [Mini], but it fails, print this panel to convert it to a trash bin. It will be far more interesting than your typical trash bin, and it saves some plastic from the landfill!

Print this panel, drop it into the lamp shade, and now you've got a trash bin. (you can use it for more prestigious things than trash if you prefer)
Print at 0.25mm layers with 15-20% infill such as with Gyroid, 2 perimeters. You can use the .3mf attached for a Prusa Mini starting point.
