The Modular Parametric Shelf is a fully customizable 3D-printable shelving system designed for maximum flexibility, strength, and efficient material use. Built from four parametric core components, it allows you to create an endless variety of shelf configurations perfectly tailored to your space.

Every dimension, thickness, and honeycomb structure can be adjusted directly in the Makerworld configurator, giving you full control over strength, weight, and appearance.

Core Parametric Components (Default Values)

1. Legs / Supports

Adjustable height, diameter, and internal cutouts for screws or connectors.

• Height: 50 mm
• Diameter: 5 mm
• Internal cutout diameter: 2.5 mm
• Partial cutout height: 8 mm

2. Top Covers

Clean finishing plugs with customizable parameters.

• Height: 8 mm
• Diameter: 5 mm
• Hole diameter: 2.5 mm
• Partial cutout height: 5 mm

3. Bottom Plates

Fully configurable base plates with integrated screw posts.

• Length: 100 mm
• Width: 70 mm
• Thickness: 3 mm
• Screw post: Ø 2.5 mm × 5 mm height
• Post offset: 3 mm
• Frame thickness: 4 mm

4. Main Plates

Lightweight yet strong shelves with customizable honeycomb structure.

• Length: 100 mm
• Width: 70 mm
• Thickness: 3 mm
• Screw hole diameter: 2.5 mm
• Offset: 3 mm
• Surface: Honeycomb or solid
• Default honeycomb: Hexagonal, 6 mm cell size, 1 mm wall thickness
• Honeycomb frame: 4 mm

Key Features

• Fully Parametric Design
  All dimensions, hole sizes, wall thicknesses, and patterns can be adjusted directly in the configurator.
• Customizable Honeycomb Patterns
  Choose between hexagon, triangle, square, or custom shapes. Optimize for strength, weight, or material savings.
• True Modular System
  Legs, top covers, bottom plates, and main plates can be freely mixed and matched – no fixed layouts.
• Optimized for 3D Printing
  Designed for PLA, PETG, ABS, and ASA. Fast print times and low material usage thanks to the parametric honeycomb structure.

Advantages Over Static Version

• Fully parametric instead of hundreds of static files
• Adjustable honeycomb structure and thickness
• Modular end-caps, connectors, and hole placement
• Infinite configurations without file management chaos

Recommended Use

Ideal for:

• Desks and home offices
• Small apartments
• Storage rooms
• Workshops and tool organization

Easily adapt size, strength, and structure to your exact needs while maintaining printability and durability.

⚠️ Important Printing Notice

The design features a tight tolerance of 0.1 mm.

• Fitment depends heavily on your printer's calibration.
• If the parts are too tight, you may need to use a drill to slightly enlarge the holes or adjust "Hole Horizontal Expansion" (XY hole compensation) in your slicer before printing.
• If the fit is too loose, a drop of glue can be used (though it is designed to work without it).

Parts List:

1. Main Platform (min. 1 pc) – The surface for displaying your items.
2. Legs (min. 4 pcs) – Feature a pin on top and a hole at the bottom (for connecting to the base or stacking).
3. Bottom Plate / Frame (Optional, highly recommended) – Greatly improves stability.
4. Caps (Optional) – Aesthetic caps to cover the top pins if you are not stacking another level.

Assembly Instructions

1. Prepare the Base: If you printed the bottom frame, place it on a flat surface. Insert the 4 legs into it (hole facing down, pin facing up).
2. Mount the Platform: Place the main honeycomb platform onto the leg pins. Press down evenly.
3. Finish:
   • Option A (Single Stand): Place the caps on the protruding top pins for a clean look.
   • Option B (Tower): Instead of caps, insert another set of legs into the top pins to build a second level!
