Add-on city for the Moonlit Atlas book

Paris

A tower built for the 1889 World's Fair and meant to come down. It is still standing, and now it stands up in your book.

Paris, folded flat inside a Moonlit Atlas book. Scroll to open it.

Press the brass button. The lid lifts, and three rows of Paris stand up with it: the quay, the Seine and the skyline.

The foot of the tower. The arch between its legs was the gateway to the 1889 World's Fair.

It was due to come down after 20 years, until its radio mast made it too useful to lose. Here it stands 128 mm tall, the tallest piece in the set.

Lights out. The platforms, the beacon on the mast and every window in Paris glow on their own: glow-in-the-dark filament, no batteries.

The same Paris, printed

Each photo starts from a render of the real CAD. An image model turns the render into a print, and a checker throws out any picture that adds or changes a part. Your own print's layer lines and colours will vary.

With the room lights out, the windows, the stars, the tower's two platforms and the beacon on its mast glow.

Walk it row by row

The set is three rows of buildings and a plate of water. Drag to turn the book, and tap a number to read that landmark's story.

It goes into the book you already have

New York out, Paris in

The Moonlit Atlas book comes with New York standing in it. Each row clicks onto its frame with two magnets and two V-keys. Lift it straight up and it comes free.

With the three rows off, lift the New York harbor plate out of the tray.

Drop in the Paris plate, with its bateau-mouche and péniche on the Seine.

Set the Paris rows on, back to front. The grooves slide over the keys and the magnets pull each row home. Going back to New York, or on to another city, works the same way.

What you print, and what it needs

The Paris pack

Three building rows and a harbor plate, printed in 35 color regions, plus 6 disc magnets (6 × 2 mm) that hold the rows on their frames. The CAD lists 41 parts in all.

Tallest piece, the Eiffel Tower
about 5 in 128 mm
Filament
123 g of PLA, slicer estimate 4.4 oz
Print time
5 h 16 min, slicer estimate
Building depth
up to 0.47 in, so the rows fold flat 12 mm

It needs the book

This pack is a city and nothing else: no tray, no lid, no springs. It works only in a Moonlit Atlas book, which is sold separately and comes with New York. Paris drops into the book's tray and clicks onto its three row frames, and it swaps with any other city set.

For the printer

  • A 0.4 mm nozzle and multi-material for the color regions.
  • Windows, the tower's platforms and its beacon are glow-in-the-dark PLA inlays, 0.8 mm deep. They glow brightest for 30 to 60 minutes after a lamp has charged them.
  • Rows print on their backs with the fronts up, and the plate prints flat. Every part fits a 256 × 256 mm bed: the largest row is 164 × 122.5 mm, the plate 194.4 × 65.6 mm.
  • The smallest details, like the padlocks on the bridge, are 1.2 mm wide.

Press the brass button, and the tower that was meant to come down stands up again.
