Episode 3 Lucas Trenton office

I've found all but the last two items. There's evidently something to do to open or otherwise disclose these two items but I can't for the life of me figure it out! The hint button doesn't show anything so I'm stuck. Any help?

Click the blueprint on the wall. Theres a mini game. Did you click on the lipstick, the needle, and the bottle. ITEMS: Stamp- on the left side desk near wall, Lunchbox-on same desk, Scissors-on the chair of same desk,Nut&Bolt is under that same desk, Toolbox- top shelve over desk on back wall, Hammer-against file cabinet under that desk,Screwdriver is on top of the paint can, Tape measure is on top of desk on the right.

Thank you+++, I was stuck in the same place... your help is much appreciated!

I can't seem to find the needle anywhere! Help!
