(ancient) pin lock
thingiverse
I designed this model of the oldest known locking device, drawing inspiration from Maker's Muse's thought-provoking video. He shared a downloadable .STL file in the comments section, but I took it upon myself to create this design from scratch.\r\n\r\nYou can find the video that sparked my creativity at https://www.youtube.com/watch?v=GdPKQWK7jPk.
