NANO BLANK Panel 16HP Modular System

Eurorack BLANK Panel 16HP — Clean, Gap-Free Rack Layout

The NANO Modules BLANK Panel 16HP is a 16HP-wide Eurorack blank panel designed to occupy empty module slots in any standard 3U Eurorack case. It closes the visual gaps that appear when a module is removed, when a row is only partially populated, or when a builder is reserving space for a future addition. The NANO Modules BLANK Panel 16HP is the right choice for Eurorack users who need a clean, professional-looking rack without spending money on unused circuitry.

Beyond aesthetics, the panel also acts as a light physical barrier, reducing the amount of dust that settles on the case interior and on the tops of PCB-mounted components in neighbouring modules. For performers who frequently swap modules, a blank panel keeps the row looking intentional instead of half-finished.

What Sets This Blank Panel Apart

What makes this panel stand out is its 2 mm ultra-low profile depth, so it sits flush with neighbouring modules. The panel ships with two M3 knurled screws — the same "knurlies" hardware favoured across the Eurorack world — so installation is a hand-tightened job that needs no screwdriver. The face carries a subtle Lissajous-curve-inspired graphic that matches the minimalist look favoured by most module designers.

Width and Pitch — Filling the Right Gap

HP (Horizontal Pitch) is the standard Eurorack unit of module width, where 1 HP equals 5.08 mm. Choosing the correct blank-panel width is the single most important decision when tidying a rack, because a panel that is even slightly too narrow leaves an unsightly slot and one that is too wide simply will not fit. The 16HP size is well suited to medium-sized gaps — for example, the space left after removing a dual-oscillator or a small sequencer — and is one of the most useful sizes in the NANO Modules blank-panel family.

• Width: 16 HP — covers medium gaps in a 3U row
• Depth: 2 mm — sits flush without intruding on neighbouring modules
• Mounting Hardware: 2 × M3 knurled screws (included) — tool-free hand tightening

Case and Format Compatibility

Eurorack compatibility means the panel fits any case built to the standard 3U row format with M3 mounting rails, including the popular Doepfer A-100 style cases, skiff-format cases, and integrated utility cases such as the NANO Modules CAIXA 104. Because the panel is purely mechanical and carries no circuitry, it does not consume any power-supply capacity and does not need to be connected to the case bus board.

• Format: Eurorack 3U — fits any standard 3U row
• Compatible With: Eurorack cases and rack rows with M3 rails
• Power: None required — passive mechanical panel

Build Quality and Installation

The minimalist face gives a clean look that blends with most module aesthetics, whether the surrounding modules are black, silver, or anodised aluminium. The included M3 knurled screws thread directly into the standard Eurorack rail nuts, so the panel can be added or removed in seconds during a patch session. NANO Modules sums the family up as "Keep your rack clean" — a reminder that a tidy rack is both a visual statement and a small layer of protection for the modules inside.

• Panel Type: Blank panel — Lissajous-curve-inspired graphic
• Tagline: "Keep your rack clean"

Who the BLANK Panel 16HP Is For

The NANO Modules BLANK Panel 16HP is the right choice for Eurorack builders who need to fill medium-sized gaps in a 3U row and want a clean, finished look. It suits users with partially populated cases who are still planning their system and want to reserve space for a future module, as well as performers who regularly swap modules in and out of a touring case and need the row to look intentional between gigs. Beginners assembling their first rack will find the simple, tool-free installation especially approachable.

The 16HP size is also a good match for users who have removed a larger module — such as a multi-voice oscillator or a complex sequencer — and want to keep the option open for a future replacement without leaving a visible hole. Because the panel is passive and unpowered, it can be added at any time without affecting the rest of the patch.

NANO Modules — A Valencia-Based Modular Workshop

NANO Modules is a young company from València, Spain, focused on the design of modular synthesizers and other Eurorack-related products. The team's stated philosophy is to surround life with useful and well-designed items as a means to increase creative potential, and the blank-panel family — available in 2 HP, 4 HP, 6 HP, 8 HP, 12 HP, 16 HP and 20 HP sizes — is a direct expression of that minimalist, function-first approach. Alongside the blanks, the catalogue includes utility modules such as MAR, FONT, ALT, ONA, QUART and SERRA, plus integrated cases like the CAIXA 104, giving the brand a coherent identity across both accessories and full modules.
