So this is based on my sometimes-faulty memory, but here's some things that I could remember from my rec list...
Coming Home (http://archiveofourown.org/works/434870) which has Tony participating in "fool Cap about the era" and takes place at a rehab hospital where Tony's designed prosthetics. I believe it's a war veteran hospital.
Pretty sure scifigrl47's The Act of Creation Will Be Your Salvation (http://archiveofourown.org/series/18990) series has plenty of creations, most of her stories do.
As it says on the tin, 5 Gadgets Tony Invented for SHIELD (+1 he didn't) (http://archiveofourown.org/works/449547)
His Fate Will Be Unlearned (http://archiveofourown.org/works/1055361) by scifigrl47 has - amongst other things - a mini-Dummy that Tony makes for Steve.
