Razor Disposal Unit

I bought a box for my husband to dispose of his razor blades from his safety razor in and realized I could design one in Tinkercad and see if that was better than the one we paid for. This is only my second time designing something in Tinkercad or ever, so I am hoping it all works out!

It printed beautifully on the side and fits the razor blades no problem, when the box is full just slap some tape on the front and throw it away. Enjoy!

Thing should be printed on its side.

Edit: I moved the hole for where the blades go in and resized the top.
