There are many rugged boxes out there but I wasn't able to find a circular one, so I created this. Some hardware is required for assembly:

• 1 M2 12mm bolt
• 1 M2 Nut
• 1 M3 20mm bolt
• 1 M3 Nut

To assemble press the M2 nut into the appropriate spot on the lid, then add the latch and thread the M2 bolt through. Place the lid on the compartment and secure with the M3 bolt and nut.

I put some effort into making the model parametric and would definitely be open to requests for different sizes or any other feedback.
