Cufflink Coin Backing

I like the look of the crest on the coins on cufflinks, but could no longer find the metal ones to fit the One Naira coin, so I designed and printed my own. Was challenging to get the end of the cufflink to turn till I realised - bridging! - so didn't need supports at all for that part, and it worked perfectly on the 6th iteration. Each one is a quick 45min print, with minimal post production. There is a longer stemmed stl file for double-cuffs and a shorter stemmed one for single cuffed shirts. Amend the size of the cradle in Fusion 360 to fit your coin diameter.
