Gregory's Serverit turned out pretty well, i printed it with a 0.3mm extruder on my Ender 3. it also fit the lock!

  @tubetime Even with tumbler disassembly, I'm so surprised you got it to work. I also wonder if it's cheaper to have a locksmith make a key from that or try to use it for a mold. @tubetime I guess you could get a metal key cut from it at the local hardware. @tubetime your Medeco Biaxial key reverse engineering feels like something @deviantollam would be interested in. He might also be able to suggest where you could get a suitable metal blank to suit your pinning (or to suit a repinned version). (3D printed sintered metal probably also isn’t strong enough for frequent use, but a metal key cast from the negative of your reverse engineered key model might be sufficient for light use.) @ewenmcneill @deviantollam i found his video on the pinning tray, so that was helpful. @deviantollam @ewenmcneill thanks for the kind words. right now it is just some random notes and a crappy solidworks file. i am not convinced i have the depths right. i also have another lock (with no key) of very similar make, so i'll probably take that one apart and compare the pinning @tubetime Wow. This is genius. Amazing work. Thanks for sharing.  @tubetime Pretty impressive reverse engineering there. Impressive! First idea would be James from Clough42 on YouTube. He seems really skilled with 3D CAE and delicate CNC machining.  @tubetime you’ve already got a working model for an FDM printer, so I’m wondering if this would also work in a SLS metal printer? No idea what the cost of the print would be though. Or you could have a go at making a high temperature silicone mould of the key and casting it in pewter.  @tubetime neat! Could you get an outfit to print you a copy in metal with DMLS? I have no idea how much such a thing would cost @tubetime Nice work! Now that you have the shape, it could be possible to cast it in bronze :) |
using an iterative process i wound up with this key.
