Supports & Printing Notes

• Large footprint make sure your first layer is dialed in

If your first layer is off, this print will tell you immediately.

Assembly Notes

• 
• Fold all four sides of each cell inward on itself before placing into the tray
• The cells will flex into shape — don’t force them
• Warm plastic folds better
  • If the print is fresh off the bed, it’s ideal
  • If it’s been sitting in a cold shop, warm it slightly before folding
• Cold prints are more brittle and can snap during folding

Important Notes

• Manual watering required (no self-watering system)
• Not designed for high-heat environments (PLA may deform)
