Instructions: You're about to make a highly customized model with the following settings: Screws have diameters of 2.1 mm. There are no washers present. A slot is located in the middle, offset by exactly 3.0 units from the center. The nut grid is confined to one row on the y-axis, which holds a total of 1 piece. Similarly, there is only one nut arranged on the x-axis in a straight line. Washers are cylindrical in shape with a diameter measuring at 4 mm. Slots are designed to be fairly narrow, stretching just over 11.5 units long. The space occupied by the nuts spans an average width of around 7 units. All edge heights for the slots remain exactly at 1 unit high. Nuts extend in depth from their base surface at approximately 3 units on average. Lastly, the combined length covered by a series of placed nuts stretches to about 16 units, rotating each time at roughly 30-degree intervals throughout. Slot Total Height has reached the maximum height allowed which measures exactly 3.4 mm
