Top details

Shape
Tip

The contact ball is fitted tangent to the body, so any radius prints seamlessly. Small spins with less friction; large survives drops and rough floors.

Three-part print

Always on: one-piece tops balance on a cooling pinpoint and fail on most printers. The top and bottom halves each get a threaded socket, and the short stud prints as its own part before coupling them. The eye button switches between the assembled top and the print layout.

3MF color
52 x 66 mm
Up to 28 g in PLA printed solid
Tip cone 39°, balances at 38% of height
3 separate parts, flat faces down, no supports

The Bambu / Orca 3MF opens with the top half, bottom half, and threaded stud already placed: 40% concentric infill, 4 walls, 0.12 mm layers, random seam. STL works in every slicer.

Printing notes

  • The split print lays out three separate parts: bottom half flat rim down with tip up, top half flat rim down with stem up, and the threaded stud standing upright. The broad flat faces hold the plate without a brim, no supports are needed, and the Bambu / Orca export keeps the 0.12 mm layers and random seam tuned for clean spinning surfaces.
  • 40% concentric infill with 4 walls beats solid in spin tests: the walls concentrate mass at the rim where it stores momentum, while a solid core mostly adds tip friction. Concentric lays every line as rings around the spin axis, so the mass stays balanced. The Bambu / Orca 3MF export sets this automatically, with 0.12 mm layers and a random seam.
  • The three-part split is what makes any tip radius printable: the tip belongs to the bottom half and prints last above a wide flat disc, while the separate stud screws into sockets in both halves after printing.
  • The silhouette is a totem-style top, the same shape made famous by the spinning totem in Inception. Twirl the stem hard between both palms and let it run.
  • The tip cone stat shows the included angle at the contact point. 60 to 90 degrees is the rugged zone; smaller is sportier but leans on a more delicate neck.
