Endless Calendar

Last week one of my students send me this link of this Endless Calendar asking me that could we make this using a 3D printer. Woodworking has not yet started for these 5th graders. Tinkercad is a pretty safe option for them. I loved his idea and decided to give it a try using Tinkercad.

In this assignment, students will use Tinkercad to construct their own endless calendar. I have leveled this assignment according to the skill level of my 5th-grade students who have just started 3D designing and have basic knowledge of using Tinkercad.

This project will further sharpen and strengthen students' measurement, perception, and logical thinking skills which is vital for 3D designing.


Things We Need

1) Computer with an internet connection

2) Tinkercad account


Copy and Tinker

With each task, I have shared the templets. Please click the template link provided with each task, login to your Tinkercad account. Then click on the "Copy and Tinker" icon on the left. The task will open, rename your design by clicking the "Change Name" box at the top left.

Now, we are ready to go.


Let's Tinker: Calendar Date Box: Task 1

Templet For Task 1

What: For this task, students have to insert the hollow cuboid inside the bigger sold cuboid so that we get solid cuboid with an empty pocket at the top(see pic 2 above). Now, motivate the students to tinker so that we have a solid cuboid with two equal empty pockets, 10mm apart with a thickness of the cuboid box 5mm on each side(see pic 3 above).

How: In the First picture above, notice that the hollow cuboid has some dimensions marked in red circles. Students will need to adjust these dimensions accurately in order to complete this task.

Hint: L, B, and H = Length, Breadth, and Height of hollow cuboid. Z= height of hollow cuboid above the working plane. X and Y are the distance of the hollow cuboid from the X and Y axes. Dimensions of solid cuboid

157mm x 57.50mm x 52mm


Let's Tinker: Calendar Date Box: Task 2

Templet for Task 2:

What: For this task, students have to insert the hollow tower at the junction of the two hollow pockets (see pic 2 above). The end result should look like the one in picture 3 above.

How: Students should alter the X and Y measurements to complete this task successfully.

Hint: Dimensions of middle solid cross-section 10mm x 28mm x 60mm


Let's Tinker: Calendar Date Box: Task 3

Templet for Task 3:

What: For this task, students have to insert the hollow cylinder at the lower left and upper right face of the solid cuboid to construct 2 circular windows 1 and 2(see pic 5 above). The window should be in the middle of the faces and 10mm from the top and bottom.

How: Rotate the cylinder to 90 degrees on its axis and tinker with its dimensions to successfully complete the task.

Hint: Keep in mind the dimensions of the solid cuboid.


Let's Tinker: Calendar Date Box: Task 4

What: For this task, students have to construct a lid and date tiles for the date box. Further, they will also write the numbers on the date tiles. The numbering should be clearly visible from the circular window.

How: Simply drag a solid cuboid to the workplace and alter its dimensions according to that of the date box.

Hint: Lid: Dimension of date box. Date Tiles: Inner dimensions of the date box. Dimensions of the tiles should be such that there is a space of 2mm around the stacks of the tiles once they are inserted inside the box.


Let Tinkering Continue: Months and Year, Boxes and Tiles

Now that students have learned to construct the complex Date box with its tiles, its time to push them further and let them tinker to contrast the complete Perpetual calender.

The prize for my student will be: Getting their design 3D printed. They will Love it !!

Table Toy

  Tinkercad is well suited for students as it not only introduces us to CAD but also helps us to practice some mathematics lessons and therefore, I like using Scale while designing on Tinkercad. I'll be making a Mini Dustpan and Brush Toy for my study table.  This will help me to keep my study table clean from Rubber/Eraser dust and Pencil shavings. Things We Need Laptop or Computer Internet Connection Tinkercad Account 3D printer, filament and a paper cutter (if you are printing) Designing Dustpan Log in to your Tinkercad account and click  3D Design  (Left of your screen). Then click on   Create new design . Click and drag the   ruler   (Top right of your screen) to the   W orkplane . Keep the workplane snap grid measurement to 1.0 mm (Bottom right of your screen). Now, click on   Box   shape under   Tinkercad basic shapes   menu (Right of your screen) and drag it to the workplane. Change the dimensions of the box to 30mm X 4...

STEAM Horse

You can find cardboard just about anywhere and for cheap, if not free. It’s versatile, easy to use, and an excellent teaching tool. At my home and school this the first thing that I like to give to the kids so that they get the opportunity to embrace STEM activities with a simple and inexpensive material: cardboard. In this project, I'll share how to make a Cardboard Horse and make it run with the help of Power Of Science, without any battery or wheels.  "This is my opening lines in the class before I start with this activity." Time Required: 45  min What:  Horse made out of cardboard which will move with the help of fluid pressure. Why:  Hands-on fun activity on liquid pressure. How:  Read-along... Things We Need 1) Cardboard 30cm*30cm 2) Glue Gun and Glue Sticks(2sticks)  3) X-ACTO knife  4) 2 10 ml Syringe  5) 1 foot of clear plastic tubing that fits the syringe tips  6) A pair of Scissors  7) 1 Toothpick piece  8) Straw, One, 2c...

The Circuit Bug

Circuit bugs are a simple and fun way to introduce children to electricity and circuitry and tie them with a STEM-based curriculum. This cute bug incorporates a great fine motor and creative crafting skills, working with electricity and circuits that will keep your kids enthralled and challenged. Things We Need 1) 2 LED Lights. 2) Insulated PVC coated wire. 3) Batteries – CR2032  3V. 4) Electrical Tape. 5 Clothespins. 6) Pipecleaners/chenille sticks 7) Wirestripper. 8) Plier. Cut and Remove End to End Coating If you have a thick wire you can use wire strippers but if you have a thin wire you can cut the wire using scissor. Cut your wire in equal lengths. Cut after measuring the length of the wire equal to the length of the clothespin. It is recommended to cut it a bit long and trim it later to the final length. You want enough length for a good connection but not too much that you raise your risk of circuit interruption. Have students cut their wire into four equal pieces. Show stu...
