Kristian’s Stargate project

I have a made a “working” Stargate model from the SG1 TV-show. It spins, the chevrons move and lights up and when a correct address is dialled, the wormhole is established. The wormhole is an infinity mirror effect. The stargate is controlled with a DHD. You can check out the video presentation of the Stargate in action here:

Here is a video showing one Stargate dialing another Stargate

I like 3d printing, electronics, programming and making stuff. I also enjoy the Stargate TV-series and decided to make a “working” model of the stargate as seen in the TV-show.

This was a challenging and fun project and I had to learn a lot of new stuff. This has been a very time-consuming project. There are a few variations of Stargates used in the show and I chose to make the original one from the SG1 series. There are also several logical “glitches” in the technical workings of the gate as seen in the TV show and it even behaves differently in different episodes. I have made it work as best I can while staying as true as possible to the feeling and essence of the TV-Show.


  • A fully interactive working Stargate complete with a DHD (Dial Home Device).
  • The Stargate ring spins and places the dialled symbol on the correct chevron as the traveller is inputting the address by using the DHD.
  • All 7 chevrons move and lights up when engaged.
  • The Stargate can dial any milky-way address used in the show.
  • NEW: The stargate can now dial other stargates over the Internet, and receive incoming wormholes from other stargates on the Internet.
  • When a correct address is input using the DHD, the wormhole is established.
  • The wormhole effect consists of a animated infinity mirror of 122 LED’s.
  • Complete with sound effects from the TV Show.
  • When the wormhole stays open, selected random audio clips from the TV-Show is played.
  • As in the TV-Show the wormhole can stay open for 38 minutes. When the time limit is reached, a random quote from the show where the time limit is mentioned is played and the wormhole disengages.
  • Do not dial the black hole.
  • The Stargate itself is about 39 cm in diameter.

  1. This just came up in my Facebook feed. Is this you or someone ripping off your idea? [link removed]

  2. 04/12/2021 None of the above comments are dated. Found this on Facebook and was wondering if it was you or not? [link removed] I’ve seen too many fake sites on facebook to believe in this link. If it’s you I have friends waiting to know. They would like very much to purchase one.

    1. The amethystly store is a scam. They simply stole the video and text from this site. Ordering anything on that store will not get you a Stargate. Sorry.

    2. What an amazing project! Great work.
      However, I found you because a company on Facebook has stolen your video and much of your text, and is claiming to have 36 of these in stock for sale at $79USD. What a bunch of scam artists! And taking the work of a REAL artist is terrible.

    3. Bonjour,

      Le projet est impressionnant, je suis fan !
      comment puis-je acheter une porte des étoiles avec un DHD ?
      est-il possible également d’avoir une seconde porte pour la liaison entre la première porte ?
      Combien couterait le tout ?

      merci de vos réponses


      The project is impressive, I am a fan!
      how can i buy a stargate with a DHD?
      is it also possible to have a second gate for the connection between the first gate?
      How much would it all cost?

      Thank you for your answers

    4. Hello, your gate is amazing!
      I want to build my own gate, but there is a problem.
      “Micro Metal Gearmotor with Push Header Shim – 50:1 (x7)”
      Is there a replacement for this motor? This is out of stock on most sites.
      Thank you

      1. I think maybe other stargate builders are buying them all. And that’s why most sites are out of stock. I have not researched for replacement motors. But if you find one, it should be very similar in speed/torque and size to give you the best fit. If it’s very different you might need to tweak the code to correct speed issues etc. I tried a few variations of speed/torque before i settled on the 50:1 ratio. Faster motors was a bit weak, and stronger motors was a bit slow. The 50:1 seems to do the job nicely.

      1. Hi Szilárd Szabó,
        The plants and grass are not 3D printed. They are bought from a hobby/model/paint shop. The plants are hand painted though.

    5. Hi Kristian
      I just have to say WOW and YES I get to build my own!! Great at building not so great at painting but I will learn.

      When you have time few questions
      1-What are your printer settings for the 3D parts (Like infill)
      2-I read you used ABS can you provide the part number for filament’s used to print please.
      3-Did you vaper smooth all of the parts? (main seen Gate parts and stars)
      3-Where did you get the PCB board made?

      Printing test part as I am sending you this.

      Thank You


      I am a big Stargate SG-1 fan and was wondering if you would be willing to sell one of these beautiful and authentic Stargate models. Let me know…thanks.

      PS: I can see you’ve been asked this many times :). Your work is incredible!

    7. I am in the process of making my own and was thinking I may aswell and make 2 while I am at it. I was wondering if it was possible to make them connect wirelessly? What I mean I want to dial on one to activate the other and vice versa, also if anyone knows how to set up audio transmission so I can dial and talk through the gate too would be amazing!

    8. I want to buy, please buy me my dad is a big fan of Stargate and watched every season many times for years please want to buy immediately for my father’s birthday …

    9. You have done an amazing job on your Stargate. Do you have any kind of guide or step by step and maybe a complete parts list so I can try to build one myself. Also, the wiring and programming for the DHD control would be nice as well. I have a cartesian 3d printer that I am quite good with but I just got a large delta style that I want to use to print the parts. I saw your prices for the stl files and also for the DHD board so I will be getting most of it I could probably get it put together by myself but the wiring and programming might be tricky.

      Again it is an amazing stargate, I congratulate you on a well-done project and look forward to maybe seeing more.

    10. I’m probably sure you’ve been asked many times, but do you produce these to order? If so , how much would one cost?

    11. I am a big fan of this project and am very impressed by your work. I have dabbled with PCBs through JLCPCB and have used Arduino a lot. I’ve even programmed standalone ATMega328P circuits. I just got into 3D printing and this gate project is one I would like to do. I’ve only ever printed using PLA material so far. I can definitely learn how to use ABS filament for printing. I was wondering, do you know if ABS is required or would PLA work as well? Did you use gray filament for the prints that didn’t require clear material?

      1. Hi Jonathan!
        I am glad you like this project. I think it will be perfectly suited for you! I use exclusively ABS material myself. But I know other builders use other materials also. PLA and PETG mostly I think. I used gray or silver for most of the parts (except the transparent parts). The color of the material don’t matter much If you paint it in the end anyway. 🙂
        We have a community of gate builders on Discord. You will find the invite link in the downloadable archive. Hope to see you there.

          Thank you. Buying the file archive right now. Thanks for answering my questions.


      2. Do not turn off all lights at the same time while turning it off. Let it be closed one by one from the end.

      3. Just awsome! I would love to buy one of them! Really beautiful work and everything! If you are interested I can give you a free hosting space and 10 gigs of space for free for infinite time for free. The servers are in Slovenija (Europe) 1Gbps/1Gbps.

        Take care and Stargate forever! 😀

      4. Hi, great project but I see one mistake there. If repaired, it could make production a lot easier. In the movie, the Stargate enters by rotating the selected symbol to the upper chevron. He then makes a move and the corresponding chevron lights up. In other words, the moving chevron is just the first. The others are static. So there would be no need to change anything in the 3D files, just to redesign the programming and electronics. Basically, a single motor with a gearbox for shevron would suffice.
