The Tilted Modular Wine Rack is a fully modular, tool-free wine storage system designed to scale cleanly with your collection.
It stores both standard wine bottles and larger champagne-style bottles at a fixed 8-degree downward tilt, ensuring the cork stays wet at all times.

The rack is built as a rectangular grid, where each position holds exactly one bottle.
You can build any M × N configuration, where:

• M = number of rows (horizontal, bottom to top)
• N = number of columns (vertical, left to right)

Each grid position corresponds to one bottle. From small countertop racks to large wall-sized layouts, the same parts and rules apply.

Design Overview

Each bottle module consists of:

• 1 front frame
• 1 back frame
• 4 single end connectors (left, right, top, bottom)

The back frame features a narrow neck slot that locks the bottle in place and prevents sliding, even with the 8° tilt. All back frames are identical. Front frames come in two variants:

• Base front frames → used only on the first (bottom) row
• Regular front frames → used on all rows above

Both front and back frames are designed as a circle inside a circumscribed square frame, providing excellent rigidity while accommodating both regular and large-diameter bottles.

Optional Parts

The base front frames have two slots accomodating standard ½ inch cabinet door bumpers, as listed below.

• ½" Cabinet Door Bumpers (3.5mm tall, 2 per base frame)

Modular Connection System

Modules are connected using a double dovetail connector system, creating a very rigid structure without glue or screws:

• Left + Right double dovetail connectors → between adjacent columns
• Top + Bottom double dovetail connectors → between adjacent rows

On the external perimeter, single end connectors are used:

• Left end
• Right end
• Top end
• Bottom end

There are no redundant parts and no extra stiffeners—strength comes entirely from geometry and tight dovetail engagement.

Design Goals

This rack was designed to meet the following requirements:

• Fully modular (scales to any M × N size)
• Supports both regular and large bottles
• 8° tilt to keep corks wet
• Very sturdy and rigid
• Bottles lock in place without sliding
• Front frames available with or without label slots
• No glue, no screws, fully mechanical assembly

Smaller racks can also be used as portable bottle carriers, safely lifted by holding the top middle connector.

Printing Notes

• Easy to print
• Minimal supports required for:
  • Dovetail connectors
  • Front frames with label slots
• No special materials required

Several print profiles are included for common configurations:

• Large bottle racks: 1×1, 1×2, 2×3, 4×10
• Small bottle rack: 2×3

Assembly Instructions (Important)

For racks where M > 1, assembly must follow a specific sequence due to the tilted dovetail geometry.

Recommended procedure:

1. Start with either the leftmost or rightmost column
2. Begin from the front base frame in the bottom row
3. Build upward, installing all M front frames and required connectors for the given column
4. Once the full column is complete, enclose it from the back:
   • Install the top back frame first
   • Continue downward until the bottom back frame is installed

If this sequence is not followed, the tilted dovetail connectors will prevent proper installation.

Part Count Formula (Any M × N Rack)

If you want to build a rack for any MxN dimensions, use this formula to calculate the number of each part you will need:

Feedback Welcome

I’d really appreciate feedback from anyone who prints this—especially regarding assembly flow, connector tolerances, label usability, and overall rigidity.
If you build one, please share photos and let me know how it worked out 🍷
