After printing the first model of the box I noticed just how flimsy the design was so I revamped the design to be less flimsy

Improvements to notice:
"pin" now goes through the internal of the lid allowing for the lid to reinforce the "pin"

"pin" now has 2 bars so it would need to break in 2 places before failing unlike the single pin of the MK1

No cylinders, the lock pin part of the design is now rectangular so it should be much easier to print

Optional having the individual parts in separate files to make it abit more user friendly for people with smaller printers

Note:
You still need to source your own lock or in this case 2 if you want to use both lock points

The design is by no means perfect and as such can still use improvement

supports would be a bad idea for printing this as the area that would actually generate supports (the pin shaft in the lid) would be an absolute nightmare to remove said supports
