Microfluidic Positive Master Mold

Create a 3D model of a positive master mold for a soft lithography microfluidic device. The model must consist of a main base plate with positive raised geometry protruding $0.075~mm$ ($75~\mu m$) from the top surface. All units are in millimeters. The geometry must be merged into a single continuous solid body. 1. Base Plate:Shape: Solid rectangular block.Dimensions: $75~mm$ (length) $\times 50~mm$ (width) $\times 2~mm$ (thickness). Position: Centered at the origin.2. Main Raised Compartments (Extruded $+0.075~mm$ above the base): Left Co-culture Compartment: $1.5~mm \times 1.5~mm$ square. Right Co-culture Compartment: $1.5~mm \times 1.5~mm$ square, placed parallel to the right of the left compartment with a $1~mm$ gap between them. Astrocyte Compartment: $1.5~mm \times 3.0~mm$ rectangle, centered horizontally below the top two compartments, separated by a $1.25~mm$ vertical gap. 3. Maze Structures (Extruded $+0.075~mm$ above the base): Create two vertical connecting channels joining the inner bottom edges of the top two compartments to the top edge of the bottom compartment.Inside each connecting channel, create a staggered, interlocking maze pattern consisting of 10 rectangular banks (5 pairs). Each individual bank rectangle is $0.05~mm$ wide and $0.25~mm$ long. Arrange them in two vertical columns facing each other. The horizontal gap between the inner tips of the opposing banks must be exactly $0.15~mm$. The vertical gap between rectangles in the same column is $0.05~mm$. The opposing column must be vertically offset by $0.05~mm$ to create an interlocking zipper pattern. 4. Reservoir Punch Targets and Channels (Extruded $+0.075~mm$ above the base): Create six solid circles, each $6~mm$ in diameter. Position two circles diagonally above the left compartment, two diagonally above the right compartment, and two diagonally below the bottom compartment. Connect the center of each $6~mm$ circle to the nearest corner of its respective rectangular compartment using a straight channel that is $0.25~mm$ wide. Ensure all intersecting lines are trimmed so the circles, channels, compartments, and mazes form one continuous, seamless raised fluid volume.
