Stackmelt was designed around color from the very beginning. Instead of treating multi-color printing as decoration added after the model was finished, each layer of this shelf becomes part of the geometry... stacking, flowing and dripping into the layer beneath it.

The result is a functional wall-mounted display shelf that looks somewhere between molten material, stacked paint and a piece of pop-art sculpture. It was created especially with multi-head and multi-color printers in mind, where deliberate color changes can become a feature rather than something you try to hide.

Key Features

Designed for Multi-Color Printing: The shelf is intentionally divided into bold visual layers so color changes enhance the actual form of the model.
Multi-Head Printer Friendly: A great showcase piece for printers capable of running multiple materials or colors without turning the model into a purge-heavy collection of tiny color details.
Sculptural Drip Geometry: Each layer flows independently around the front and sides, creating a deep three-dimensional melting effect rather than a simple color stripe.
Real Functional Shelf Surface: on top of the chaos is a clean, flat display surface suitable for figures, collectibles, small electronics and decor.
Full 3D Treatment: The melting geometry continues around the corners and underneath the shelf, so it still looks intentional from lower and side viewing angles.
Hidden-Hardware Appearance: Once installed, the mounting hardware stays visually out of the way so the layered geometry remains the focus.
Color-Scheme Friendly: The sample uses four contrasting colors, but Stackmelt is meant to be experimented with. Try gradients, monochrome shades, neon combinations, earth tones or entirely different materials.
Color Zones: 4 in the pictured configuration
Hardware Required: Wall screws and anchors appropriate for your wall type

Built for Multi-Head & Multi-Color Printers

This model started as an experiment in designing for the capabilities of modern multi-head printers instead of simply adapting a normal model to them afterward.

The broad color regions are deliberate. Rather than hundreds of tiny decorative color swaps, Stackmelt uses large, intentional material zones that visually describe the construction of the shelf.

Installation

Print the components using the supplied orientations and recommended settings.
Install the appropriate wall anchors and screws for your wall material.
Mount the shelf securely and verify that it sits flat against the wall.
Test with lightweight objects first before adding your final display pieces.

I wanted to make something where having multiple colors wasn't just a slicer trick, it was the entire reason the object looked the way it did.

Stackmelt is basically what happens when a functional wall shelf forgets that it's supposed to behave itself.

If you print one, I really want to see the color combination you come up with.
