Sounds like a great idea—tactile play is gold for visual‑impaired kids. Make sure every piece has a distinct texture and shape, and add braille labels or tactile markers so they can identify parts by touch. Also think about the assembly process: give clear, step‑by‑step audio cues or a simple audio guide. Keep the colors high‑contrast if you’re using any visual cues—just in case someone’s partially sighted. And test with actual users to see if any textures feel too slippery or hard to grip. You’ve got a solid start; just fine‑tune those little details and it’ll be a hit.
