So i was asked by a co-worker to print a key for his wife's 45th birthday, i found the Medieval Key made by Sevro and used it as a base, i split the model in to 2 parts to make it easier to print scaled up and to allow the addition of a collar on the key which covers the join, i also modelled a basic stand for displaying the key and added a little basic sign board for people to write what they like, don't worry about the text on the one in the photo the model in the 3mf file is blank for you to add whatever you want to it :)

And in the spirit of sharing i've uploaded this remix of the model
