Functional Print Material Guide

  • PETG for wet/food areas: Fridge dispensers and kitchen organizers should use PETG. It's food-safe when printed correctly and handles moisture without warping.
  • PLA+ for dry storage: Nail polish organizers, CD racks, and record holders use PLA+ - no environmental stress, so no need for PETG's extra properties.
  • Threaded connections: The capsule container's thread requires 4 perimeter walls and 0.2mm layer height for the threads to engage correctly. Do not reduce wall count.
  • Wall mounting: All keyhole mounts are sized for M4×20mm screws. Use wall anchors rated for 2× the expected load - shelf loads shift and spike with real use.
