10K Club Interview: WORKING POLAROID SUN 600 LMS by Julien G12

Welcome back, everyone, to another 10K Club Interview. Today we introduce Julien Guillochon, a.k.a. Julien G12, and his fantastic WORKING POLAROID SUN 600 LMS. A man of many talents, clearly, aeronautical engineer Julien has created a most impressive build. Let Julien know what a fantastic job he has done!



  1. Who are you?
    My name is Julien Guillochon. 

  2. Where are you from?
    I come from Laval (France). 
  3. How old are you?
    I’m 25 years old. 
  4. What do you study or do for a living?
    I’m an aeronautical engineer.  
  5. What hobbies do you have?
    I’ve got a lot of hobbies: cinema, triathlon, flying (I’ve got my private pilot license) and obviously LEGO building. 
  6. Do you have a personal LEGO portfolio website that you can share with us?
    I don’t have one for the moment.  
  7. Have you created any LEGO MOCs (my own creations) that you’re particularly proud of? What is it, why are you proud of it and do you have a photo of it?
    I’m very proud of my first project that I uploaded on LEGO ideas. The set is based on “Interstellar” (my all-time favourite movie). I succeed to bring together earth and black hole scenes in one set with a secret feature. It took me a year to find the correct way to do it. 

  8. How and when did your interest in LEGO products come about?
    I received my first set (2229) at Christmas. Then, I had a lot of Star Wars and Harry Potter sets to play with. Later, the software brought me back to the LEGO World. For 3 years now, I’m buying sets again to display them. 
  9. What is the LEGO hobby to you? What does it mean to you? How does it fit in your life? E.g. build, display, meetups, play the games or 'just' watch the cartoons.
    When I was younger it meant creativity for me. I was always mixing parts from different sets to create new stories. I remember using Harry Potter’s wand part as a black lightsaber for my Star Wars stories (it was the ultimate lightsaber!)
  10. What is your favourite LEGO theme (current or past)? Why? And has any theme inspired your building style or preference in any particular way?
    I’m sorry but I can’t choose only one theme. When I was a kid, it was Star Wars. Now, I’m more interested in Ideas and Creator Expert.
  11. What is your favourite official LEGO set ever? Why?
    LEGO Saturn V (21309). I’m passionate about the Apollo mission and this set is the perfect one (even the number of pieces is perfect: 1969).

  12. What is your favourite LEGO element? Why?
    The hinge plate 1x4 swivel base and top (2429 and 2430). I love to create secret rooms and this part is very useful.
  13. Is there a LEGO designer (official LEGO designer or fan designer) who you are inspired by and look up to? Who and why?
    Not a particular one, but I’m fascinated by LEGO designers and LEGO Ideas members, people have so much creativity.
  14. Is there one or more particular LEGO-related websites (not official LEGO websites) that you visit often and/or are inspired by?
    “Hoth Bricks” to keep me informed of LEGO news and reviews.



  1. Where did your interest in this particular model come from?
    My girlfriend uses a Polaroid to capture our best moments.  It’s definitely way better than smartphones. The shot may not be perfect, but there are always some unexpected details that make it special. I thought it could be a great set. I chose the Sun 600 LMS because it is the most iconic one.  

  2. How long was the process of making the project, and what did you have to research as well? What kind of prep, research and design phases did you go through to produce your creation?
    The Polaroid we have is a new generation one. I had to do some research to have the Sun 600 LMS dimensions. After that, I converted the dimensions into LEGO dimensions. Then I began my project on software. I created a big cube with basic bricks and I deleted some parts to have the correct shape at the right dimensions. 

    Next, I designed all the details. The final step was to create the mechanism.  

  3. What special challenges did you face creating the model? What was the most difficult part to recreate?
    Definitely the mechanism; the system had to be easy to use and fit in the Polaroid.
  4. If you could talk to yourself before you started on this project, what would you tell them? What do you know now that you wish you knew then? 
    Don’t be focused on one idea. Try to find other solutions. It took me a while before thinking of the spring part for the mechanism. 
  5. How long did it take to complete the model? Did you finish it fairly quickly, or did it take a long time? And how did the build time compare to the time you spent promoting your Product Idea to reach 10,000 supporters? 
    The design took me 3 months. I didn’t have to promote it, I quickly reached 10,000 supporters.  
  6. How did it feel when you reached the magic 10,000 votes and how long did it take? 
    I was so happy. I would never have thought of reaching it so fast! I had 100 more supports every day. I thought that it would reduce, but I was wrong. The LEGO ideas predictions have been correct.  
  7. Approximately how many LEGO bricks did you use to create your model?
    There are 822 parts. 
  8. What is your favourite building technique or part/section that you’ve incorporated into your Product Idea?
    I think this is the light system part. The opening/closing is quite realistic, it perfectly fits. I’m also quite proud of the mechanism. 

  9. If you built your model digitally, what software did you use to build and render your model? software.
  10. If you used custom stickers or prints for your design, how did you create them or where did you get them? 
    I found the picture in a free image library on the internet. I made the other stickers by myself with “Microsoft Word”. The stickers were added with “ part designer”.  



  1. Do you have any useful advice about creating a successful LEGO Ideas project?
    Invest yourself 100%. All details matter.
  2. What (if any) methods did you use to advertise and attract support to your Product Idea? 
    I didn’t promote my project. I only replied to comments.  
  3. What is your favourite LEGO Ideas Product Idea (besides your own of course)? Are there any Product Ideas you think have been overlooked?
    Up - Missing You…by aleehc was so beautiful, you can feel emotions across the set. 
  4. What is it about the platform that attracts you? What tips would you give to anyone who is thinking about uploading an idea?
    Creativity. It keeps fascinating me every time. 

    The quality of the pictures you upload is very important. You could design a very nice set, but if the pictures don’t show off your project, it won’t have as many supports that it deserves.
  5. Do you have plans to submit any other Product Ideas in the future? If yes, can you give us a hint of what that might be?
    I’m working on something very different. My idea is very clear in my mind but technically it’s quite difficult to realise. I need to spend more time finding the way to build it.
