A four legs platform

Task / Preparation

The assignment consisted of creating a 10 x 10 x 10 cm plywood object using press fit assemblages in order to understand the design logic of this technique and also the possibilities of the laser cutting machine. The only constrictions were that the object should not be a box and neither a toy.

Design Process:

In order to achieve the task, I first concentrated in understanding the press fit concept and the kind of assemblage I wanted to use using Pinterest boards and web research. 

With the understanding than Press fit assembly consist in creating friction between contact surfaces  of separate objects I thought about generating an element whose structural behaviour could be very clear and could reflect the different kinds of strengths that a pressfit connection can allow. So I just intersected two perpedicular planes and start to think what they could become.

Then, while I was cleaning the kitchen of my dormitory and listening to music from my cellphone I realized I wanted to have a support where I could put it so it would not be in contact with the table or it could float inside a cooking pot to amplify it sound so I decided to design a small platform. 

And I began to design the final object using rhino. 

The final object was functional and some interesting details where achieved like the “floating” appearance from the round piece but some calculation mistakes were donde since I did not prevented more accurately the size of the laser and how much material it burns. With very small objects its better to do simpler connection that make the piece work as a whole like the central ortogonal connection.

Class: Technology

Machine: Raylogic AS-1290C

Software: Rhinoceros 6

Material: Plywood, thickness: 3,6 mm


  • 3 types of connections between parts: insert into the hole, slide and insert into the groove
  • you can make real bench using this drawings


  • Unstable construction
  • Problem with proportions
  • Too thin

Class: Technology

Machine: Laser cutter

Software: Autocad 2018, Rhinoceros 5

Material: Plywood; thickness: 3,6 mm

Size of the object: 30*25*14 cm

Challenges:learn how to work with laser cutter, how to use AutoCad 2018 and use correct scale in Rhinoceros 5


The 1sttask was dedicated to creation of own press-fit projects using plywood details of 10*10. Core idea was to familiarize students with software used and get first experience with laser cutting objects.

As advised on the class I dived into Pinterest to find a good idea. My attention was drawn to a simple though practical laptop stand and I used this concept to do one of my own.

It’s ready to use.

Class – technology, laser cutting

– AutoCAD
– 4 mm birch plywood

Laser cutting machine, Raylogic AS-1290C

Prototype small individual project by brainstorming, drawing, and laser cutting.

– 10x10x10 cm space
– Press fit
– Not a toy

The main objective of the task was to learn how to come up with good ideas, how to develop it, how to use graphic design programs, and, eventually, how to use laser cutting machine.

I wanted to create something light, stylish and mindful. After brainstorming the possibilities I understood that wooden sticks can be a good element of the work – they are really functional and strong. Plus, you can map a lot of them even in the limited space. The idea of bench was simple and smart, because benches are common elements of the city landscape. 

First stage was sketching:

Processed with VSCO with h3 preset

Then I tried to draw elements, which later would be created in graphic designer:

As my graphic skills left much to be desired, I turned to classmates who taught me how to use AutoCAD. Eventually I got this design:

In order to make the connection of sticks tighter, i decided to reduce holes by 0.1 mm from each side.

Finished dwg-file was opened with software and send to laser printing.

Produced elements were easy to assemble and the connection was so tight, that no glue needed.

SOFTWARE: Rhino 6, LaserWorkV6

MATERIAL: Plywood 100*100*4 mm

MACHINE: Laser Cutting Machine Raylogic AS-1290C

CHALLENGES: Create something press-fit


The task sounded quite simple: create something pressfit using plywood. This task had a goal to develop our skills in Rhino and Laser cutting.

As far as we had only one material and small size of this material, I decided to make a two-sided keychain to make people on the streets happier. I had an idea to write something inspirng, which ended in “Hey, You! Smile ;)”.


The sketch of the key chain came into my mind in the metro, so I decided not to waste my time and draw it in Rhino.


After saving my file in .dxf format I passed to the computer, which is connected to the Machine. I open the file with “File – Import” and placed it on the “surface” of the Laser Cutter.

I had to make two layers:

  • general layer of cutting (Speed 9mm/s; Power 95.0);
  • layer for “printing” (Speed 200 mm/s; Power 30.0).

First layer cutted the key chain itself, second one was slightly burning the plywood to “print” the letters.

“Printing by Laser cutting machine”

Because of the problems with the machine, I had to cut it twice. Because of that, the size of connecting sticks was smaller than the holes. I had to use glue to connect it.


As a result of the work, I created a key chain, which is actually is not a press-fit thing. The idea itself was not a press-fit from the start.

Laser cutting is a simple and cheap (materials) technology to create prototypes.

The task allowed me to understand the main principles of working with Rhino and the laser cutting technology itself.

As an overall result, I can now give people another reason to smile, when they see my key chain on the backpack.


Students are required to document their work each class section for the unit covered and homework will be reviewed during each class cycle. Your local tutor will review your documentation in detail every week to make sure you are not falling behind.

Your Technology course documentation must show completion of the unit and core skill competencies. It will be in HTML format and must be able to exist within a web blog archive.

At minimum, the evaluation process expects a student’s documentation to include:

  • A text description of their project for the class section or group project
  • Designing and fabricating the work
  • Supporting photographs (video is great, but not required)
  • All final fabrication files in their original, editable formats
  • All code in an editable format, testable format
  • What the student learned: what succeeded and what failed

It is recommended that students choose a licence for their work prior to the start of publicly posting their files. ie: Creative Commons

Student must share all of hers\his digital design files and code (where applicable) to pass the unit.

Here is a good (but not perfect) example of a blog post.

Student Responsibilities

It is your responsibility to be proactive in the Technology course. This course offers a great deal of personal freedom. 

However you are responsible for:

  • Designing and fabricating your own projects
  • It’s fine to begin with someone else’s files, but it is not acceptable to pass someone else’s work off as your own.
  • Cite all your sources and inspirations.
  • Getting your work done on time for each weekly cycle.
  • Documenting your work in HTML
  • Ensuring that your documentation is in the blog system. Work that is not in the system will not be evaluated.
