Being challenge to make something tiny, I decided to make a tiny coffee house out of cardboard and some 3D printing items.

Supplies

Here are the supplies for this project:

Cardboards

Hot Glue gun

Scissor

Ruler

Pencil

Plastic film

Some Acrylic paints and paint brushes

Tinkercad Software and internet connection

3D Printer

PLA Filaments (blue, white, and black)

Step 1: Preparation of Making Walls, Roof and Floor

For making walls, roof and floor for the coffee house, take the cardboard. Make square shape for the floor with the side of 14 cm each and side of 12 cm each for back wall.

Make rectangle shape for other sides. For side walls, the length is 12 cm and width is 6 cm.

Step 2: Walls

To make it interesting and pretty, I used brick wall texture to cover all the walls. Click here for the source.

Print the texture on paper and cut it out. Glue it on the walls one by one.

Step 3: Window

Cut the middle of the right side of the wall with the dimension as shown in the picture. Glue with plastic film (in the inside part) as if for the window glass. Cut some small rectangles with blue paper for window panes. Glue them like in the picture.

Step 4: Floor

Choose floor texture in google search and then print it. Click here if you want the floor texture like mine.

Glue it to the floor base.

Step 5: Assemble

Assemble all the parts (floor and walls) by gluing all together. See the pictures.

Step 6: Roof

Make hole to the roof. Leave all the sides into 1 cm each. Cover it with plastic film on the bottom side. Glue the roof to the coffee house.

Step 7: Painting

Paint the roof with acrylic paint. The color is your choice.
First, I choose brown color. Later at the end, I change the color into green because turnout, the green color is prettier than brown.

Also, paint the list of the floor. I paint with black color.

Step 8: Cashier Counter

Open Tinkercad.com for making cashier counter. The counter is consists of 3 boxes. Construct it into a table. For the measurement, the height is 40 mm, the length is 52.5 mm and the width is 42 mm. After finish, group them together and export it to .stl files. Then, print to 3D Printer.

Do Google search and make logo for your coffee house. I use this site to make my logo. Make a screenshot to Microsoft Word. The height and width are 0.7" each. Print and glue it to the front of your cashier counter.

Glue the cashier counter to the coffee house.

Step 9: Menu Chalkboard

Find a nice chalkboard style for displaying your menu.

I used this site. Copy and paste it to Microsoft word. Make the height 1.42" and width 2". Print it to paper and cut it.

Measure the same measurement to cardboard and cut it.

Glue the menu chalkboard on the cardboard.

Step 10: Chalkboard Display

Find by googling a chalkboard display. I use this site.
Copy and paste it to Microsoft word. Make the height 1.24" and width 1". Print it to paper and cut it.

Measure the cardboard with the measurement as shown in the picture. Make it 2 pieces for front and back. Cut it.

Glue the chalkboard display on the cardboard and glue the other part to the first one until it forms like triangle.

Step 11: Logo

For logo to your coffee house, use the same logo as previous step. The height and width are 1" each. Print and glue it to the cardboard.

Step 12: Sign

Also make a coffee house sign. It is up to you to make the
design. I use word art in Microsoft Word. Print, cut and glue it to the cardboard. You can see the picture for the size of the cardboard.

Paint it with acrylic paint to make it prettier. I paint with green color.

Step 13: Coffee Table

For making the coffee table, I prefer to make it in Tinkercad. Use 2 cylinders (for top and foot) and 1 paraboloid for base. Make sure the height is 25mm and the diameter of the table is 20 mm. Export to .stl file and print it.

Step 14: Assemble

Glue the cashier counter, sign, chalkboard display and coffee table to dollhouse by using hot glue gun. See the picture.

Step 15: Cup

For making cup, use Tinkercad. Make sure the height is 15 mm and the diameter is 20 mm. Export to .stl file and print it twice.

Step 16: Shelves

Grab cardboard. Cut into rectangle shape. The smaller one is 6 x 2 cm and the longer one is 7 x 2 cm. Paint it with acrylic paint. I choose brown color.

Step 17: Chair

Get the cardboard ready. Make shape like in the picture.
Glue the back, front and bottom parts all together. Make 2 chairs. Paint them into brown color.

Step 18: Bottles

For making bottle, use Tinkercad. Use 2 cylinders and bevel it. Make sure the height is 24.5 mm and the diameter is 15 mm. Export to .stl file and print it twice.

Step 19: Assemble

Glue bottles and cups to the shelves. Then, glue them to the coffee house.

Also, glue the chalkboard menu, coffee table and chairs to the coffee house.

Step 20: Donut Rack

Grab cardboard. Make it with the size that shown in the picture. Paint it with yellow color.

Step 21: Donuts

For making donuts, I use white buttons. Take 2 buttons to make 1 donut. Glue them together and paint it.

Step 22: Displaying Donut

Put donuts on the donut rack by gluing them using hot glue gun. Arrange them nicely.

Step 23: Computer

To make a computer for cashier, I use Tinkercad. I am using 2 boxes for the monitor and 2 cylinders for the base. The height of the computer is 25 mm. The base is actually cylinder, but arrange it into ellipse shape with the measurement is 18 mm and 25 mm. Group them together and print it.

Glue the computer to the top of cashier counter. See picture.
