Design a Sturdy Box

Creating Thick-Walled Objects

Walls need to be at least 1.2mm thick for FDM printing!

Task

  1. Create a Box for the outer shell (4×4×2 units = 40×40×20mm)
  2. Position it on the build plate
  3. The default solid box has infinitely thick walls - perfect for printing!

Remember

  • Minimum wall: 1.2mm (3 nozzle widths)
  • Recommended: 2mm for strength
  • Our solid boxes are always printable!
For hollow objects, you'd need to ensure shell thickness in your slicer software.
