Thanks to @ChukFlanagan's feedback, there was an issue with a model accessory, and I made timely adjustments. The print profile has been updated, so you can now print with confidence. For friends who encountered issues, I have separately uploaded the profile for this accessory so it can be printed individually! Thank you all for your support!

Friendly Reminder:

🧼 Please be sure to clean the build plate before printing:
Due to the rich details of the model and many small objects, to ensure printing success rate, please be sure to clean the build plate! Clean the build plate! Clean the build plate! Important things are said three times.
💡 Recommended Cleaning Method: Gently scrub the build plate surface with warm water + dish soap (the kind used for washing dishes) and a sponge. Then rinse with clean water and dry with a clean, lint-free cloth. This effectively removes grease and dust from hands, making the first layer adhere more firmly. Do not touch the cleaned build plate surface directly with your hands!

Background Introduction:

Deep Reef Defense Fleet · Blue Crab

Model: V-W03-HP "Blue Crab"
Positioning: Port cargo handling / Container stacking / Can clamp anything
Crew: One pilot
 

Background

The most common handling mech in Deep Reef Free Port. Two mechanical arms, each with two claws—not fingers, but claws. It can grip standard containers, scrap ship steel plates, and even a colleague's lunch box forgotten on the dock. The blue paint job is not by design; it's because the port's procurement department acquired a batch of blue anti-rust paint from a second-hand market and hasn't used it all yet. Orange accents on the tips of the claws and the rear warning lights are the only unified painting elements at Deep Reef Port—not for aesthetics, but so you can see where it is in dense fog.

Story

The Blue Crab pilots of Deep Reef Port have an unwritten rule: when the claws are lifted, whether they've gripped something or not, pause for one second. Because the last person who didn't pause crushed a box of live crabs into two boxes of dead crabs. Afterward, he wrote a note in the cockpit: "Claws are not hands; they are opinions divided in two." The note is still taped to the Blue Crab's control stick in Hangar #3.
