+/- MTG Counters (updated)

Updated version of my MTG counters.

• Fixed some major issues with the previous designs, which made them difficult to slice
• Made them lay close to each other, to save time on travels.

For convenience, I've made available both a single-piece STL and an STL containing 64-counters to print in bulk.

Feel free to use them at FNM, but be sure to tell them where you got em <3
