Smooth Cards Case/Box (Backpack proof)

I've made a new and improved case, check it out!A smooth closing cards case that survives being thrown around in a backpack. It holds even though there is no snapping mechanismTrust me I tried ⬇️That case was thrown, slung and shaken around the living room for a solid 3 minutes with no signs of it opening. PrintingIf you own a printer with mid to high tolerances I would go for the tighter one as that one also guarantees that the case will function after much wear. There is also an optional version with smooth corners (like the yellow one in the images). PS: I've also made a matching case for UNO cards: https://makerworld.com/en/models/558707#profileId-477869Matching UNO case v2!
