I’m experimenting with BumpMesh, a tool that applies tactile, fidget-friendly textures to 3D-printable models. The photo above shows several test prints, each carrying a different texture, from a fine pebbled grain to large rocky bumps and a ridged band.

The goal is to build up a working understanding of which textures print cleanly on an FDM (fused deposition modeling) printer and read well by touch. That knowledge is meant to feed into tactile map making, where distinct, reliably printable surface textures can help distinguish map features by feel.
