3D Printed Digit Puzzle


I was looking for some design ideas for my half-yearly designing project when I came across this puzzle made on Pinterest. I loved it and decided to make it for my submission.

This puzzle is not only fun to solve and beautiful to see but also apt for beginners like me.


Things We Need

Tinkercad account(It's free)

Slicing Software

3D printer

Filament of choice (I used Blue and Black)


Digits 8

I started by designing digit 8 first simply because it is easy to make among other digits and it may be used as a base to make other digits, as you will notice later.

To make digit 8:

  1. Drag a sold Box to the workplane and adjust its measurements so that its Length to 40 mm, Width to 24 mm, and Height to 8mm.
  2. For the inner holes of the 8, use two hole cube with Length and Width = 8m and Height = 10mm.
  3. Now, drag 2 hole Roof and rotate them so that they are pointing toward the main body of digit 8.
  4. To cut off the corner, use 4 hole Box and rotate it at a 45 degree
  5. Finally, select all the shapes and group them together.


Digits 3, 5, 9

In this step, we will use 8 designed in the previous step and design 3, 4, 5, and 9.

Digit 3(Pic 1):

Copy and Duplicate 8 and select hole. Then overlap it with solid 8(Pic 1). Group them to get digit 3.

Digit 4(Pic 2):

Make 3 copies of 8 and select hole. Arrange and overlap it around the sold 8(Pic 2). Select all the shapes and group them together.

Digit 5 and 2 (Pic 3):

Make a copy of 8 and select hole. Now, rotate it at 90 degrees and arrange it as shown in Pic 3 above. Select both the shape and group them to get digit 5.

Make a copy of 5 and rotate flip it to get digit 2.

Digit 6 and 9 (Pic 4):

Make a copy of 8 and select hole. Arrange it as shown in Pic 3 above. Select both the shape and group them to get digit 5.
Make a copy of 9 and rotate flip it to get digit 6.


Digits: 0, 1, 7

The digits 0, 1, and 7 were a little tough for me as compared to the digits in the previous steps. Here is how I designed them.

Digit 1(Pic 1):

I started by designing digit 1 first. For this first, we need to group a solid 8 and hole 3 together. This will result in a shape that resembles two hexagons stacked one above the other. Group this with a solid box of Length = 20 mm, Width = 5 mm and Height = 8 mm.

Digit 0(Pic 2):

For digit 0, group a solid 8 with a solid 1 and hole 1(rotated horizontally) as shown in Pic 2 above.

Digit 7(Pic 3):

To get digit 7, arrange overlap, and group together a solid 3 with a solid 1 and a hole 6 as shown in Pic 3 above.


Puzzle Box

For the puzzle box, first, drag a solid box to the workplane and adjust its dimensions to Length = 88mm, Width = 72mm, and Height = 11mm. Now, arrange and group 4 hole digits 8 on the four corners of the solid box(pic2). Now, copy and duplicate this box and adjust the dimension of this copied box to Length = 94mm, Width = 78mm, and Height = 8mm. Select a hole for this box and rise it 3mm above the workplane.

Finally, align and create both the boxes together.

The Digit Puzzle is ready to be exported and printed.

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...

STEM Bubble Wand

  Everybody loves bubbles, regardless of age. But why all the bubble wands needs to be flat and bubble always spherical. In today’s project, we will break these stereotypes and build some 3-dimensional bubble wands and learn structural engineering. We'll also make an inverted bubble cube that mimics a tensile structure. These simple demonstrations will introduce basic geometric shapes and complex engineering concepts to kids, visually. Things We Need Plastic straws Pipe cleaners A pair of Scissors Bubble Solution, Homemade  or store-bought. Bigmouth bowl or container (not in the picture above) Pyramid Bubble Wand To built this Tetrahedron (Pyramid) Bubble Wand: Cut six straws of 2 inches each. Thread a pipe cleaner through one straw and bend the end of the pipe cleaner to secure it at the end. Then thread two more straws onto the pipe cleaner. Bend the long end of the pipe cleaner back to meet the starting point and twist the two ends around each other. Add two more straw sect...
