What it does

  • Modular 2-inch alphabet blocks perfect for custom signs and displays
  • Heat sink-inspired design with 1mm walls for reliable printing
  • Includes alternate letter designs for creative typography projects
  • Stack, arrange, and rearrange to spell any message you want
  • Industrial aesthetic adds modern edge to shelves, desks, and walls

Each character features a heat sink-inspired design that's as functional as it is striking, making these 3D prints ideal for personalized signs, desk nameplates, or statement home decor pieces.

The geometric design uses precise 1mm wall thicknesses that print cleanly on standard 3D printers, ensuring crisp details and structural integrity. The iterative, layered appearance creates visual interest from every angle, while the modular format lets you rearrange letters endlessly to suit your mood or message.

This complete alphabet set includes bonus alternate letter designs, giving you flexibility for custom typography projects. Whether you're spelling out a favorite word on your bookshelf or creating dimensional wall art, these stackable blocks transform simple letters into interactive 3D printed home decor.
