3D Printed Watch With a Hidden Compartment

What if your watch could do more than just tell time, what if it could also be a compartmentalized timepiece. In today’s fast-paced world, personal accessories are evolving to meet our ever-changing needs. Among these innovations, the Compartmentalized Timepiece stands out as a remarkable blend of style and practicality. With this watch on your wrist, it is not just a tool for telling time; it’s a multifunctional accessory that is designed to enhance our day to day lives. Not only this timepiece redefines what a watch can be, but also offers users a seamless combination of elegance and utility.

Inspiration: This product was inspired by other makers in local markets and websites, where it could also be found in online retailers like Amazon and specialized watch retailers. One of the websites can be found here, and also can be found here Overall, my main inspiration was by looking at bulky watches in-store, thinking that it could also make a good thing to stash anything small inside, for our day to day lives.

1. 3D Printer around your area
2. 3D Modeling software
3. 2 pieces of a thin wire (optional)
4. PETG Filament or any other
5. Measuring Tape
6. Small Magnets

First, you got to dimension the center circle with a diameter of 1.70 inches, this would be the storage inside the watch. Be sure to add some distance from the end of the watch and the center, for full stability for the watch once it's printed. Then, you will dimension the lug for the watch, which has the length of 0.80 inches. The very important thing for this design is to add dimension for the watch to the edge, to allow the watch straps to have a full range of motion, which has the dimension of 0.25 inches, by 0.15 on the side. Then, after you have made the full sketch of the base for the timepiece, you will have to extrude it by 0.40, which should look like the second picture above.

After making the base, you will need to create a path upward with the same circle you did base with the dimension of 1.70 inches. If possible, add a second plane above the base with a distance of 0.30 inches for the timepiece base. You will sketch on the plane you've added on then add the circle coincident from the base of the previous sketch you've done, with the same dimension of 1.70 inches. Then you will have to use the base as a first reference, and the sketch of the circle as the second reference for the Loft Extrude to work. Which should look like the second picture above.

Design a hole approximately 0.12 inches in diameter, then place in the middle at 0.12 inches from the edge of the lug.

In this step, you will create a hole for the storage you plan to put in. You will need to sketch on top of the face, from the loft you've just created. Set an offset from the same circle you've sketched for the loft, with a distance of 0.2 inches. You will then Extrude Cut by 0.56 inches, which should look like the second picture above.

You will have to include Loft Cut, to create a pattern for the lid to lock in place, you would need to make to cuts. One cut should be vertical to the other, inside the cut you have just made.

Create another part, which would be the lid, with the same dimension of the circle that was used for the Extrude Cut. Once you have sketched the circle, extrude it by 0.3 inches, then add two small cylinders on either side to create a self-lock mechanism.

In this step, you'll need to create in a new part, then sketch a rectangle with the dimensions of 0.76in X 0.30in. You also need to design a flap on one side of the rectangle, in order for the rectangles to connect to each other, this is very important. You will then sketch out a guideline with the dimension of one side of your appropriate wrist length. In order to calculate the right watch strap, is to measure your whole wrist in inches. Then subtract that measurement by 2 inches from the timepiece, then subtract that by 1 inches for the magnet to fit in the compartment you'll create. After you have done that, you will divide that exact number by two, since there will be two individual watch straps for either side. That would be the dimension of your guideline.

You will then use a Linear Pattern feature to make copies of that rectangle with a spacing of approximately .25 inches (use the picture above as extra reference), towards the end of the guideline. You may then get rid of the left line for each rectangle you make, in order for the watch strap to work properly.

After doing all that, make sure your sketch looks like the sketch above.

Once you have done the previous step, you may then extrude it by .085 inches upward. Then make another sketch on top of the feature and copy all of the rectangles that you made, EXCEPT THE FLAPS, then extrude it once more by .085inches. After that, copy the rectangles once more, you only need the outside lines of each rectangle, but this time you CLOSE the rectangles. Then you may extrude it by .05 inches, so the watch is already covered. Lastly, you will mirror all of the three features to the other side. After mirroring, the watch strap should look like the image above.

ALSO, extrude a small rectangle, which the magnets would go, in order for the watch straps to close on each other, once you already put it on.

Design a circle with a diameter of 0.11 inches in diameter, then extrude it by 1.10 inches in diameter, This would help connect the watch strap to the Timepiece itself. IF YOU ARE NOT PLANNING TO MAKING A PIN, you may also use some sort of wire that will perfectly fit through the hole and through the watch strap.

You will need TWO pins or wires in order to assemble them.

After Printing, you can assemble the two watch straps to the timepiece with a pin or wire. Then you can place the lid inside the watch, then twist to the left so it can self-lock.

In conclusion, this is a remarkable watch with a feature that benefits many people. It also exemplifies the perfect fusion of elegance and practicality. It showcased exceptional craftsmanship and its discreet design allows for a secure storage of small essentials, making it an exquisite accessory for any occasion.
