Slotted building discs

Build open-ended models from one interlocking part

40 mm discs with eight radial slots: any two push together at any slot, in line or crossed, so a pile of identical pieces becomes spheres, chains, animals and towers. One shape, endless joints; print dozens in mixed colours from leftover filament.
