This is a lock designed link your device to a fixed point (A lock).
I have made some changes for CNC frendly fabrication, so it took a while uploading.
I also changed the name to E-Lock, since Kensington will start sideeyeing me.
(Yes, I know what I said. I’ll take this down if nobody wants to see it…)
Firstly, these are open-source for community improvement.
bending/tampering resistance by the use of guards.
Front guard disallows the shackle from being bent.
The Back guard protects the back shackle from bending.
The ring guard protects tampering of the guards.
(This info below may be inaccurate since I changed partial lock design. FEM testing wasn’t used right now.)
The shackle is designed to withstand 2-7k netwons. (2k when aluminum is used, 7k if steel is used.)(This was found on the web. This may be mild/severly innacurate. Take this with a grain of salt.)
~200 Newtons are required to move a car.Also the shackle tip is round instead of square. This improves the shackle from V-bending:
Kensington Shakle tip: ====[]
My shakle tip: ====D
(Don’t throw out of context… :|)
And finally, it’s cheap and easy to make.
And this is… plastic instead of metal? Or am I misunderstanding things?
The entire device should be 3d metal printed.
If you want a lighter device. Plastic works on:
Metal is needed on:
Oh, wow. I’m obviously new to 3D printing, but you can basically replace a forged piece of steel/brass!? If so, that’s awesome!
Yes.
With PLA, you can submerge your part with sand and use molten metal. (PLA Casting)
3D printer can also print metals. You just need a special nozzle and metal fillament.
