Disk detainer padlock - thick disk add-on

Addition to disk detainer padlock https://www.thingiverse.com/thing:4573968.

I found original parts too small, too tight, too demanding for tolerances.


Intended use:
- download original model.
- print original model parts at 1.5 magnification.
- print these disks and key and spacers and use them in assembly.

Improvements:
- thicker disks - require less precision in printing (and operating)
- thicker spacers - require less precision.
- disks and spacers thickness is multiple of 0.3mm layer height.
- keyhole and key is "rounded rectangle", which works better on key turning.
- keyhole have central "hole" so that middle of key is not catching disk by error.
- keyholes have relatively big tolerance - key insertion and operation is easier.

Print note:
- i printed disks and spacers at 0.3. All details are horizontal, so no point using small layers.
- i printed key with 0.15mm with supports - to make slated working surfaces better.
