Print and Play! Desktop Rotary Polisher | For Figures, Curios, and Stones Alike

Grinding figures by hand until you get tenosynovitis, or getting wrist pain from polishing beads?
Buying a pre-made machine costs hundreds, and you still have to wait for bearings, screws, and other parts?
Newbies spend half a day assembling it with instructions, getting turned off immediately?

This zero-threshold rotary polisher, ready to use right after printing, helps you achieve complete polishing freedom!
✅ Truly Zero Additional Purchased Parts

No need to buy a single bearing or screw!
The bearing structure is directly incorporated into the print file, resulting in smooth and durable bearings when printed. If they break, just reprint them—zero-cost maintenance.

✅ Only 1 Standard TT Motor Required

This is the standard TT motor used in mystery boxes and smart cars, available for just a few dollars. Apart from that, everything else is 3D printed!

✅ 5-Minute Brainless Installation, Even Clumsy People Won't Fail

No complex alignment, no drilling or gluing, no repeated debugging.
Parts snap into place easily, so even absolute beginners to 3D printing can assemble it successfully on the first try.

✅ Threaded Dual-Hemisphere Drum, No Spilling or Leaking, Super Worry-Free

Open with a twist, tighten with a turn; loading materials and abrasives takes 10 seconds.
The threads bite tightly, preventing powder from scattering during dry polishing and water from leaking during wet polishing, so you'll never have to clean up a mess again.

✅ Built-in Mixing Blades for 360° All-Around Grinding

As it rolls, it fully tumbles the materials and abrasives, preventing accumulation and dead spots.
Fine seams of figures, textures of curios, and uneven surfaces of stones are all polished evenly and finely, far surpassing the results of manual grinding.

✅ One Machine for Many Uses, Suitable for All Scenarios

• 3D Printed Figures/Models: Remove layer lines, matte polish, mirror polish

• Curio Beads/Walnuts: Dry polish for patina, wet polish for brightening and de-oxidation

• Exotic/Rough Stones: Coarse grind for skin removal, fine grind for polishing

• Small Metal Parts: Deburring, rust removal, refurbishment
📌 Printing Tips
Can be perfectly printed with ordinary household FDM printers, no extra supports needed.
Drum recommended 20% infill, frame 10%+ infill for sturdiness and durability.

No more wasting money, no more collecting parts and waiting for delivery.
