Summary

If you want something printed, consider buying through my 3D Hub. Link: https://www.3dhubs.com/seattle/hubs/3d-life

This is a combination lock I thought up. It was inspired by (but not derived from) SavageRodent's combination lock. Use the customizer to make your own passcode for the lock. Just type in a number from 0-9 into 'numberOne' through 'numberFour' and 4 dials will be generated. Download them, and print!

NOTE: ring.scad has been fixed! It now generates 4 dials in one use.

EDIT 1/1/16: Made the teeth on the shackle closer together so the rings will be closer together.

EDIT 1/2/16: ring.scad is fixed! This no longer uses bridge2nowhere's MTG Life Counter.

EDIT 1/4/16: Before, the first and last correct digit mechanism could be seen from the sides. I have created rims on the shell, shackle, and endcap so people can't see the correct combination. Also, added a marker to shackle to show where combination goes.

EDIT 1/11/16: Before, ring.scad needed to be used 4 times to generate 4 dials. Now, you can use it once.

EDIT 2/20/16: Expanded the gap in the dials for the teeth. Also posted a pic of the finished lock that has been printed.

Assembly

Assembly

  1. Pick a 4-digit passcode. (ex. 1234)
  2. Use ring.scad to generate the four digits that you need.
  3. Print the dials, shell.stl, shackle.stl and endcap.stl
  4. Slide the shackle into the shell.
  5. Slide the dials from the back onto the shell in the appropriate order to make your passcode. make sure that the teeth go through the gap.
  6. Slide the endcap on after the dials and glue in place if it's not tight enough.

does it actually work

This is so cool. Maybe not so practical but oh so cool.

Thanks! I'm considering working on a version that could be practical, but we'll see.. Thanks for your feedback!
