⭐ Starry Gacha Machine Assembly Guide ⭐

(Experimental Model — please read the warning at the end! Also please keep in mind this is a 3D printed Gacha machine & my first 'functional' model😅💖 this model took me 4-5 weeks to finish so I hope you guys enjoy it <3 <3)

--Designed for 1.5 inch capsules.

Note: Do not overfill the machine or it will be harder to turn- leaving some space for things to move around is best!

If you prefer a video, you can find one here, but please make sure to read through this guide for instructions and tips!

✨ Step 0 — 3D Print Your Machine

Things to note:

• If you want a cleaner finish on your front star handle, please flip it the other way and add supports. It will be rougher with the star facing down, but require no supports.
• There are two star caps, please choose between the looser or tighter version. Please size it slightly up or down by .25mm-.5mm if it is too loose or too tight. This tolerance will vary after printing based on your printer and filament.
• The only multi-color piece I printed was on one layer of the star handle to add some contrast as this is one piece. You can do this on a single-colour printer by adding a layer color change pause (doing it this way will also colour the outer rim).
• Two pieces require supports as of the orientations above; the dome, and the inner spinner. If you flip the star handle, that may also require some light supports but will look better as a finished product as the visible part will be nice and clean!

✨ Step 1 — Build the Turn Handle

Grab the center spindle (the tall cylinder piece). You’ll notice a star imprint on one end — that’s the front.

• Attach the flat end (no star) to the inner spinner base (the flat disk).

• Glue is optional — it will hold without glue!

   

  

  

🔸 Important note: In my photos/videos, I did place the front star cap on early — you can do that too, just don’t glue it yet. You’ll need to remove it later when attaching the front of the machine!

✨ Step 2 — Insert the Spindle

Place the spindle into the gacha machine base so it sits centered and upright.

✨ Step 3 — Attach the Top Dome

Add a thin line of glue around the bottom rim of the dome (top piece).

Place it on the base and press straight down until it snaps in.

✨ Step 4 — Add the Side Stars (Optional)

Glue the decorative side stars into their indents.

If one doesn’t fit, rotate it slightly until it does.
Hold each star in place for about a minute.

✨ Step 5 — Assemble the Front Display Window

1. Add glue around the front rim.

    

   

   

2. Place the mesh window over it, lining up the bottom edge.

    

   

   

3. Add a second ring of glue around the mesh rim — this is what sticks it to the machine.

Remove the front star handle if it’s already on.
Press the assembled rim + mesh onto the front of the machine. Hold gently for about a minute.

Reattach the front star handle afterward (glue optional).

✨ Step 6 — Add the Ears (Optional)

If you printed the ear version, slide the ears into the side slots with a little glue.
Hold for about a minute so they set nicely.

✨ Step 7 — Seal the Back

Attach the star stopper to the back opening.
There are two types:

• Tight fit: very secure but may require a metal scraper to remove when refilling.

• Loose fit: easier to remove and still stays on unless the machine is tipped.

   

  

  

Resize the stopper by ±0.25–0.5 mm if needed.

💛 Tip: Print all parts on the same printer. Even identical printers have slightly different tolerances — but they stay consistent within their own prints!

⚠️ Warning: Experimental Model!

This is an experimental design, which means it’s a bonus model created so I can try new ideas, shapes, mechanisms, and tolerances! 🌸🧪

✨ Please expect some quirks — that’s part of the magic!

Feel free to share your thoughts, critiques, and suggestions. Depending on interest and feedback, this model may be:

• expanded,
• refined and fully finalized,
• or left as a one-of-a-kind little experiment 💫
