Unboxing the Parts and Light Kit

Here's the signature Lumibricks box, with sturdy cardboard and beautiful graphics on the cover and back of box.  Mine has a manufacture date of Sept 04, 2025!  Inside the box you will find all of the parts for the set including an orange box containing the light kit.  There are two thick instruction manuals as well.  The first manual contains 256 pages with instructions for steps 1 thru 7.  Manual number two has 148 pages and covers steps 8 thru 12.

However, If you prefer looking at screen versions of the manual, you can view or download the PDF versions from the Lumibricks website instead.



The included lighting kit contains all the lighting elements to illuminate the inside and outside of the diner and flying saucer.  There is also a small battery pack for CR2032 batteries (for the car) and a white battery pack that uses 3 AAA batteries. You will need to provide your own batteries if you plan on using the battery packs.  Alternatively, the set comes with a USB plug which can be plugged into any 3A to 5A power source.  Tweezers and a brick separator are tools which are also provided in the set.

As mentioned earlier, the Interstellar Diner set is constructed via 12 steps, and there are numbered parts bags that match each of those steps making the build process easier and more enjoyable.  There are three extra bags for the baseplates, the minifigures and specialized brick parts for lighting and whatnot.

In total, there are 38 parts bags.

Let's Build

Let's follow the 12 easy steps and build the Interstellar Diner.   

Step one builds the covered drive thru. Easy peasy.



The pink car's headlights and taillights are lit up and there is seating for 4.  I have to admit I'm not a big fan of the wings on the rear of the car.  A brick built tail fin for the car might have looked a lot better.

Now it's time to start building the diner.  This was step 3.

In step 4, there's a ton of interior detail that is added.  There's the classic red stools at the counter, diner table and a number of cabinets featuring items like a rubber duck, a camera and mug.  There's also a rack with magazines that are printed pieces.

In step 5, we wrap the curved wall around the interior.  The first led lights for the diner are added.

Moving along to step 6, we attached the second part of the base and add more table and chairs.  There's even a cool juke box.




Time to fully enclose the diner in step 7 and add some more lighting.   For extra play value, the diner can be opened in the center.  

Building the diner roof in step 8.

Completed the roof details and lighting in step 9.  Time to attach the roof to the diner.  I didn't encounter any attachment problems, but others on Facebook and Reddit have indicated that there were some alignment issues, probably due to brick placement on the underside of the roof, so do be careful in step 8 and 9.

In step 10, we started building the flying saucer. I was really excited to see how it lit up so I tested the lighting before applying the finishing details to the saucer.

Yay,  check it out, the diner is now about 95% complete in step 11.   Just a few minor details to add in step 12 and we are done!


Step 12 adds in some planer boxes with flowers, a serving cart and a couple of robots.  I love the glow from the purple and blue led lights, so cool.

The Interstellar diner comes with 4 unique Lumibricks style minifigures. Based on their outfits, three work in the diner and the the guy in the pink suit is the car's owner and customer.





Totally recommend this set for anyone into retro sci-fi themes and looking for something a little different than your standard Lego compatible modular buildings.
