This is the power of grassroots 3D printing.
Bob came into my 3D printshop with a few broken window hinges after a bad few storms. I sent them to @Russell_Hummerick as his first 3D print commission, he learned Solidworks over his time at our makerspace Kre8Now. They fit like butter after a first prototype was too weak from a one perimeter wall.
These particular hinges are nearly impossible to find as the design has been long abandoned for embedded window blinds and panes. I was surprised that they are each held in place due to the exact width of the glass and without any metal parts. I definitely prefer the modern day stuff though 
Imagine if there was someone like me, doing this for senior citizens and kids alike in every town. Just get out there and start making.
Happy memorial day y’all.
