Gravity Lock replacement

thingiverse

What? ----- Replacement for a "gravity lock" for a mid-1980s *Samsonite "Attaché"*. These small weighted hooks prevent the case from openening when upside-down. Unfortunately, there is no excessive force neccessary to snap them off by yanking the latches open. (But if the case was non-empty, you then have a serious "instant karma"... ;-) ) Why? ---- Back in school (in the late 1980s) some fellow managed to snap off one lock. Repairing it was too expensive for me, so I lived with it. After school, the case sat for more than 30 years in the attic, without hope for repairs (spare parts being long since gone). With the advent of my 3D-printer, there was now a chance. How? ---- Though I found a STL for the gravity-lock on Thingiverse, I decided to create my own. Getting the weights right, is even tougher than just the dimensions. You want the lock to close and open at the right angles. so I took measures from the remaining lock and tweaked the design, until I got it right. Notes ----- 1. Depending on your printer, you might need to drill out the hole a little bit to allow the hook to spin freely. 2. I printed it with the nose of the hook and the weight pointing *upward*. So I got the maximum strength for the "spine".
