24 in 1 Clock - a Clock Tells Time of All Time Zones. Made From Paper

The world is getting smaller and smaller, you might have a family member or friend that lives in a different time zone. Sometimes it can be confusing what time it is in another side of the earth. So I designed this 24 in 1 clock, that you can see all 24 times at one time.

Step 1: Parts and Tools:

Parts:

2 x page of 110 lb (199 g/m²), letter sized index paper

1 x clock mechanism ~ $1.5

1 x AA Battery

Tools:

A pair of scissors

Paper knife

Printer

Tape

Ruler for cutting and scoring

Step 2: How to Read the Clock

The major innovation of this clock is how to read the hours. Instead of the hour handle, I replaced it with a disc with a red spiral. The front clock face has numbers of slots that matches 24 time zones. So at where the red line meet the slot, you can read the current hour of that time zone.

The minute just works as a normal clock, since all the minutes in 24 time zones are the same :D

Step 3: Print the Patterns

There are 2 options of patterns you can download, the major difference is the clock faces:

1. Full clock face with 24 time zones and cities.

2. Full clock face with 24 time zones with no cities.

Of course you can customize the clock face with only the time zones and cities you care about. An ai file is here so you can use adobe illustrator or Inkscape (free) to edit it. You can also mark the slots where you have family and friends.

Make sure to print it out with 100% scale.

Step 4: Cut and Score the Patterns

Cut all the patterns perimeter and inside cutouts with a knife.

Step 5: Fold the Pieces

1. Fold the two rectangular pieces as holders for the clock front. Use small pieces of tape to hold the folds on the ends.

2. Fold the spacer.

3. Fold the 4 "feet" of the clock face.

4.Fold the minute handle: Make sure to score the center line, fold it, then cut the rest of the white flaps, they are there for easier folding. (You don't have to use this minute handle if you are happy with the one come with the clock mechanism).
