Hello again! This is my fifth entry to the Rods and Connectors Contest (I believe you can only have 5?). This is, as explained, a fully functioning K'nex padlock with a key to open it. I won't bother explaining how it works because the image notes will do a better job, just look at the final picture. I was inspired by KillerSafeCracker's padlock but I though it was too large so I designed and made this new mech. Overall, I was able to shave one "unit" off the side. Since this is my entry to the contest, it would be greatly appreciated if you could vote for this lock in the Rods and Connectors Contest!
