Strong Case - Lock mechanism

Update: I've added versions for different size magnets. Right now I have created separated profiles for 5x2mm magnets, 5x3mm magnets and 6x2mm magnets. 
Please print the version based on what magnets you prefer. The case was initially designed for 5x2mm magnets, as the BOM suggests. 
The version with blank top lid (no nuclear sign) is only for 5x2mm magnets.

• This storage case can be used as a pencil case or for anything else you like.
• Inside space size: 174.8mm x 59mm x 36mm (LxWxh)
• Strong build with sturdy print in place hinge. No hardware needed for the hinge.
• The case has a two part lid and each one can be opened separately.
• Magnetic lock mechanism on each lid. No springs needed, only magnets. Please check the gif animation and or images for details.
• All you need to build this are 8 magnets (4 are mandatory and 4 optional) and some glue.
• There is also a version without the Nuclear sign on the lid. ( profile “Case with Blank top lid ( NO Nuclear sign)”, for 5x2mm magnets only)

• I have added a profile with the model designed to fit the A1 Mini Print BED. This is not a scale down. It uses the same magnets(5x2mm) and same parts, only the case is a bit smaller. ( 164.8mm length instead of 174.8mm )

  From my several tests on an actual A1 Mini printer, it seems it's a bit harder to print it without having the corners lift off the build plate. I think one of the reasons are the build plate temperature set by Bambu studio when using PLA on A1 Mini. It sets it to 65C which makes the filament too soft and the corners start to lift after some printing time. 
  Please try to set it manually in the filament setup to 60C or even 55C or use a smooth build plate (instead of textured).

  Either way, please be sure to clean the print bed with dish soap before printing and don't touch it with fingers (where the model will be printed).

• added profile("Version for 5x3mm magnets") contains the normal case (with nuclear sign) but designed for 5x3mm magnets instead of 5x2mm ones. 
• added profile("Version for 6x2mm magnets") contains the normal case (with nuclear sign) but designed for 6x2mm magnets.

• You can use PLA Glow filament for the Nuclear sign (like i did it), to have it glow in the dark. 👌

For assembly, you need to pay attention to the magnets orientation, please don't rush and follow the images for assembly. 
For the lock mechanism, the magnets should reject each other. 
Everything should fit easily.

Locking mechanism should work easily (there are tolerances build in) but if it's not easily locking automatically, please move manually the pin in both directions for some time, to smooth it out.

Regarding printing profile, based on my tests with different Bambu filaments, sometimes the Brim is too close or the parts will be too big to fit together. If that is the case, you need to calibrate your filament flow. 
From what I've seen, usually people have issues because too much filament is extruded and the parts are a bit bigger than what it should be. In this case, please lower your filament flow (for example try to decrease with 0.01, or more if the difference is too big):
