This is a backup design for the ultra‑mini crab tank sunning platform I made for my son. Compared to the previous round sunning platform, the main differences are its square shape and the addition of three extra tiers on the top.

Key Features

• One‑piece, integrated print

• Extremely easy to print

• Perfectly compatible with cold beverage cups—specifically, the cold drink cups from Luckin Coffee that I use.

• You only need to add just enough water to submerge a little more than half of the steps.

• You can get creative with all sorts of unconventional landscaping ideas—just like with the round sunning platform:

  • Toss in a few small pebbles to gently weigh down the platform, preventing it from floating up if you add a bit too much water.

  • Add a touch of moss to enhance the visual depth and help secure the platform in place.

  
   

• Available in two sizes:

  • Small size: Ideal for my bean‑headed crabs.

  • Large size: Perfect for larger animals (the large size features two additional internal cavities, allowing you to place weights inside to keep the platform securely submerged).
