NANO DOME V2 — 3D Printable Clamshell Dome for ZWO Seestar S50, S30, S30 pro, DwarfLab 2 & 3 and Mini

Downloadable digital files for the NANO DOME V2, a 3D-printable clamshell dome designed for compact smart telescopes such as the ZWO Seestar S50, Seestar S30, Seestar S30 Pro, DwarfLab 2, 3 and mini

The full assembly documentation consists of two documents that should both be read: the NANO DOME V1 Instruction Manual (which covers the core dome build, assembly steps, weatherproofing, and operating instructions applicable to all instruments) and the NANO DOME V2 Addendum (which covers all the S50-class additions — the extension cylinder, tripod replacement platform, updated base ring panels, and compatibility guidance). The V2 Addendum is designed to be read alongside the V1 manual, not instead of it.

The Nano Dome V1 Instruction Manual and Nano Dome V2 Addendum can be downloaded for free here:

The V2 Nano Dome builds on the original design with three key additions: an extended base cylinder that raises the dome height by 95 mm to accommodate the taller S50-class instruments, updated base ring panels that bond cleanly to the extension cylinder, and a purpose-built flat mounting platform that replaces the S50's included tripod. Without this platform, the S50 and Dwarf 2/3 tripods would make the telescope too tall to fit inside any dome that can be printed on a standard home 3D printer. The platform keeps the build compact, simple, and achievable.

The Nano Dome V2 requires minimal tools and can be assembled with 3–4 spools of PETG filament, epoxy, and a few M4 fasteners. The files were designed and tested on an Anycubic Kobra 2 3D printer with a build plate of 220 x 220 x 250 mm. Every individual part — including the extension cylinder pieces — fits within this footprint, so the V2 is compatible with most standard-format 3D printers with a similar or larger build volume. A complete build can typically be finished within one to two weeks.

For a budget build, the Nano Dome V2 should cost approximately CAD 65–80, mainly for the extra PETG filament. This is roughly USD 47–58 or EUR 41–51, depending on exchange rates. Actual cost will vary depending on filament brand, local hardware prices, print settings, and whether any reprints are needed.

The optional equatorial wedge is included in the V2 package for S30 and S30 Pro users who want to operate in equatorial mode.

The documentation package includes:

- Reference dimensions for both the standard and extended dome configurations

- Printing guidance, recommended materials, and slicer settings

- Required printed parts and quantities for each supported instrument

- Bill of materials for both V1-class and V2-class builds

-Tripod replacement platform installation and telescope mounting notes

- Compatibility guidance — which file version to use for which instrument,

and upgrade path advice

- Optional equatorial wedge setup notes (S30 and S30 Pro only)

- Weatherproofing and UV protection recommendations

- Maintenance, storage, and troubleshooting notes

- Safety and liability disclaimers

- Photos and rendered images of all major components

This is a DIY project for amateur astronomers, makers, and 3D-printing hobbyists who want to build their own compact clamshell-style observatory enclosure for their smart telescope.

Please note: This is a digital download only. No physical product is included. The Nano Dome is a DIY protective enclosure and is not a certified weatherproof observatory product. Users are responsible for printing, assembly, installation, and safe use.
