Irish Handcuffs - V2

Hardware required: None! Circumferences:S = 16.0 cmM = 17.7 cmL = 20.4 cm Parametric Design, F3D file included if you'd like to make a custom fit! Design PhilosophyAfter a lot of people told me that the Irish handcuffs had an unsafe locking mechanism that would be difficult or impossible to open in the event of an emergency, I spent many nights thinking of how to make them safer. Inspiration for this design goes to EYESOFAHUNTER:https://cults3d.com/en/3d-model/fashion/ski-boot-style-collar I found this to be the safest and easiest to 3d print, please check out EYESOFAHUNTER for lovely collar designs with very intelligent locking mechanisms!
