MTG Commander Showcase Deckbox redesign

I have redesigned this deckbox to eliminate the manifold errors my slicer was throwing when I needed to print a new deckbox. I also added in a new feature for the lid - a small lip to help keep the lid from sliding off when in motion. The friction fit still works, but you can add 2 different sizes of lip to ensure the lid will not slide off in transit. I also redesigned the showcase front piece to more easily add/remove the card of your choice.

A standard (60 card) version can be found [here](https://www.thingiverse.com/thing:4125566)

Description of the original deckbox:

This is a 100 card deckbox for Magic: the Gathering. It can hold 99+ single sleeved cards (tested with Dragon Shield Matte sleeves), has a lid that slides on, and includes a space in the front to showcase your Commander. This can make it easier to find a specific deck in a travel case, so you don't need to take off the lid or write on the case.
