How you can help
Open the Open Requests below, look at the photo, and if you recognize the set (or even a clue — “that's definitely a Star Wars cockpit”) drop an answer. Identifications often come together from partial clues, and even a guess with the theme name helps the original poster.

Found these gray spaceship pieces — what LEGO set is this?
I found a bag of gray and dark gray pieces that look like they form some kind of spaceship or fighter. There are angled plates, a cockpit windshield piece, and what looks like wing sections. My son thinks it might be Star Wars but we're not sure. Any help identifying this set?
Old gray and brown castle pieces — which set are these from?
Bought a box of used LEGO at a garage sale and found a bunch of gray wall pieces, brown wooden-looking panels, and some knight minifigure parts. There are also turret-style round pieces and some flag elements. Looks like it could be from a Harry Potter set or maybe the old Castle theme. Can anyone help identify which specific set these belong to?
Orange Technic car parts with gears — can anyone ID this set?
I have a bunch of orange and black Technic beams, several gears of different sizes, some axles, and what looks like a differential gear assembly. There's also an orange body panel that curves — possibly from a supercar model? My teenager started this build months ago and lost the instructions. Any idea which Technic set this is?
Green botanical-looking LEGO pieces — is this the Bonsai Tree?
I received a bag of LEGO pieces as a gift but it came without a box or instructions. There are lots of green leaf pieces, some brown trunk-like elements, a dark blue round pot-shaped structure, and what appear to be tiny pink frog pieces. My friend thinks it might be the Bonsai Tree set but I want to make sure before I start building. Can anyone confirm?
Red Technic Ferrari — is this the Daytona SP3?
I'm looking at a partially built red Technic car. It's clearly a Ferrari based on the badge piece, and it looks like it has butterfly doors. There are a LOT of pieces — this seems like a big set. The red and black color scheme is striking. Is this the Ferrari Daytona SP3 or one of the other Technic Ferraris?
Lost instructions for Hogwarts Express Collectors Edition — any tips?
I bought the LEGO Harry Potter Hogwarts Express Collectors' Edition (76405) second-hand and it came without the instruction booklet. This set has over 5,000 pieces and the digital instructions on LEGO.com are 500+ pages. Has anyone found a good way to follow such long digital instructions? Any tips for organizing the build? I'm feeling overwhelmed just looking at the bag count.

How I use LEGO Technic to teach my kids real engineering
I'm a mechanical engineer and I've been using LEGO Technic sets to teach my three kids (ages 8, 11, and 14) real engineering concepts. We started with the simpler sets — gear ratios with the small cars, then moved to differential gears with the larger car models. My 14-year-old just finished the Lamborghini Sián (42115) and can now explain how a sequential gearbox works better than some of my college students. The beauty of Technic is that everything is visible — you can see exactly how the gears mesh and transfer motion. I've started a small after-school LEGO engineering club at their school. Best parenting decision I ever made.
Need instructions for a vintage 1980s LEGO space set
I found my old LEGO space set from the mid-1980s in my parents' attic. It has blue and gray pieces with transparent yellow windshield elements. I think it might be from the Classic Space theme. I can't find the set number anywhere on the pieces. Is there a way to get instructions for a set this old? LEGO.com doesn't seem to have instructions from the 80s.
Mystery medieval minifigures — what set do these belong to?
Found 6 minifigures in a box: there's a knight with silver armor and a red dragon shield, a blacksmith with a hammer, what looks like a king with a crown, a hooded archer figure, and two soldier-type figures with helmets. They all seem to be from the same medieval/castle-themed set. Any ideas?
Found a complete UCS Star Destroyer at Goodwill for $15
I still can't believe this happened. I was browsing the toy section at Goodwill and spotted a huge bag of gray LEGO pieces. Something about the distinctive wedge-shaped pieces caught my eye. I took a chance and bought the bag for $15. When I got home, I sorted through everything and realized it was a near-complete LEGO Star Wars Imperial Star Destroyer UCS (75252). Only missing about 20 small pieces — which I ordered from BrickLink for $8. This set retails for $700 and I got it for $23 total. Used LegoFinder's AI to confirm the identification. I'm still in shock.
