Catan Piece Holder - Deeper Roads, Stackable, Reference Card Holder

Printed the original design and I didn't like how shallow the road slots were, which caused me to make this modified version.

Modifications made from original:
V1
- Deeper holes to hold the roads better.
- Added stacking features.
- Added slanted insert for holding the building reference card.
- Removed some of the base material to help with removing from print bed.

V2
- V1 plus
- Angled the word Catan to face the player. Adds some more interest to the piece
- Fixed an issue with the stacking bumps (V1 and V2 will not stack together)
- Removed the empty Hex spaces on the base of the print. After a few prints I found it did not help remove from print bed much, and was adding print time without much benefit.
