LEGO 31012-3 Building Instructions

To ensure all parts are included, check the inventory list in the instruction booklet and compare it with the parts in your set. You can also use the LEGO online inventory tool by inputting the set number to verify all pieces.
If a piece is missing, contact LEGO customer service through their website. They typically provide replacements for missing parts after you fill out a form detailing the missing items.
Yes, you can wash LEGO bricks using warm soapy water. Avoid using very hot water and never put them in a washing machine or dishwasher. Rinse well and let them air dry on a towel.
Store your LEGO bricks in a manner that prevents excessive rubbing against each other. Use soft containers or dedicated LEGO storage boxes, and handle them with care during assembly and disassembly.
Use a LEGO brick separator to carefully pry apart pieces, especially those that are tightly connected. This tool helps prevent damage to the bricks and makes disassembly easier and faster.
Ensure that all connections are tight and use additional support structures such as beams or plates to reinforce weak areas, especially in larger models.

Sort your pieces by type or color and use small containers or compartmentalized boxes to keep them organized. Label each section to make finding pieces easier during assembly.
