Ruyi Jingu Bang, Seabarometer Needle Fish Tank Aquascaping Simple Single-Color Print Model

My idle fish tank finally came in handy! Taking advantage of this competition, I brought to life the Ruyi Jingu Bang underwater scene I've always wanted to make. This is a minimalist basic version, and I will continue to optimize and beautify it later.

• Scene Origin: Recreating the Ruyi Jingu Bang that Yu the Great left at the bottom of the water, with the rod deeply inserted into the sand, only revealing the upper part; the rest is left to imagination
• No Bottom, Super Practical: By not printing the bottom, it avoids print shrinkage and deformation (after multiple tests, large plates tend to warp), allows water to circulate freely within the tank with no dead spots, and saves material and print time
• Stable! Great for Planting: The sand bed and rocks (fish/shrimp shelters) have a rough, layered design, allowing substrate and aquatic plants to attach firmly. The aquascape remains stable and won't collapse after being placed in water, making it easy for beginners to use
• Zero Printing Threshold: Just print in a single color or multi-color. It comes standard with yellow sand, grey rocks, and a bronze-colored Ruyi Jingu Bang. Everyone can also freely change colors and have fun
• Aquarium-Friendly Material Reminder: I used PLA for prototyping this time. For long-term immersion in a fish tank, PETG material is recommended. It does not hydrolyze or deform, does not release harmful substances, and is completely safe for fish, shrimp, and aquatic plants
