Easy-Peasy Customizable Drawer Dividers v2

This generator divides a drawer or box into evenly sized cells or sections. You set the drawer dimensions, grid layout (rows, columns, optional special cell), divider thickness, decorative pattern, and print-size limits. Dividers automatically split into smaller sections depending on max print length, aligned with dovetail joints for easy assembly.

To further subdivide a section, just treat it like a new drawer and run the generator again with the smaller dimensions.

I wanted to make drawer dividers that print in one job with minimal filament. Also I wanted the layout to be shown in the customizer. Using these dividers gives the illusion of organization without the effort/planning other bin or divider systems require (no hate on Gridfinity). Just export the STL, split into objects, rearrange, and print.

V2 Updates:

• Horizontal dividers can still split automatically when they exceed the printable X length.
• Vertical dividers can now also split automatically when they exceed the printable Y length.
• X and Y print limits are now controlled separately with max_print_length_x and max_print_length_y.
• New decorative patterns were added: diamond ◆ and slots ▥.
• The slots pattern can be rotated with slot_angle, so it can look like straight jail bars or diagonal slats.
• Some internal cleanup/refactoring was done to make the OpenSCAD easier to maintain.

Inputs Overview:

Drawer/Divider Parameters:

• drawer_width, drawer_length, drawer_depth: internal size of the drawer.
• divider_thickness: thickness of each divider wall.
• max_print_length_x: max printable X length before horizontal dividers split.
• max_print_length_y: max printable Y length before vertical dividers split.

Grid Layout:

• columns, rows: number of cells across X and Y.
• colspan, rowspan: size of the special cell (starting at top-left).

Pattern Options:

• pattern: choose between none 🛇, honeycomb 🐝, pill 💊, diamond ◆, or slots ▥.
• pattern_border_thickness: how much solid area to leave around patterns.

Honeycomb Pattern Settings:

• cell_radius: size of each hexagon.
• cell_gap: spacing between them.

Pill Pattern Settings:

• pill_height, pill_radius: pill shape dimensions.
• pill_horizontal_gap, pill_vertical_gap: spacing between pills.
• pill_offset: stagger offset for alternating rows.

Diamond Pattern Settings:

• diamond_width, diamond_height: size of each diamond cutout.
• diamond_horizontal_gap, diamond_vertical_gap: spacing between diamond cutouts.
• diamond_offset: horizontal stagger between alternate diamond rows.
• diamond_vertical_offset: vertical overlap between diamond rows.

Slots Pattern Settings:

• slot_width: width of each slot cutout.
• slot_horizontal_gap: spacing between adjacent slot columns.
• slot_angle: angle of the slot cutouts. Use 0 for straight vertical bars or positive/negative values for diagonal slats.

Junction Settings:

• junction_width, junction_thickness, junction_height: size of dovetail junction blocks.
• dovetail_clearence: clearance added to the male joint.

Things to Note:

• Honeycomb and diamond patterns tend to take longer than no pattern or slots.
• If your max_print_length_x is smaller than the drawer width, the horizontal dividers will be split with an extra dovetail joint in the middle.
• If your max_print_length_y is smaller than the drawer length/vertical divider segment, vertical dividers will also split with extra dovetail joints.
• Run the dovetail test example first to dial in your dovetail_clearence. I like a super tight fit that you tap in with a hammer, but "loose as a goose" also works fine.
• I'm no SCAD wizard, so things might break at the extremes. If the min/max ranges for parameters don't suit you, just modify the values at the top of the file directly.
• If you want the dividers to be more fixed in the drawers, leave a little room in the dimension for a thin strip of double sided tape.

Print Settings:

• No Pattern: Use 1 wall and 5% infill to save time and filament.
  • The fit is looser this way (even with 0 tolerance). If that bugs you, you can increase the flow ratio slightly to tighten things up.
• With Pattern: Use at least 2 walls to avoid sloppy overhangs and weak pattern edges.
• Honeycomb especially benefits from at least 2 walls.
• I use a 0.28mm Extra Draft preset on my Bambu P1S.
• I also add mouse ears or a brim to help with bed adhesion, especially useful for tall dividers.
