This is a Screwtainer with an alternative design, with some additional features.

I added 3 main new features:

1. A stylish deisng to make it more appeling. 
2. Grooves on all sides to make it easier to hold / to remove the lid.
3. Added corner magnets to magnet the lid to the bottom when it's not needed

You'll need 12pcs of 8x3mm magnets and 12pcs of 6x1mm magnets.
