OpenForge 2.0 Eight Penny Base

This is an alternative base for the new OpenForge 2.0 tiles.

Devon Jones says we can design our own bases for his new stone cut tiles as long as each base is 25mm x 25mm and 6mm tall.

So here is a base meeting those requirements as an alternative to the magnet bases. Just hot glue up to two pennies per hole and enjoy the extra weight and stability -- even just 4 pennies helps significantly.

This 2x2 base weights 8 grams with 20% infill, without any pennies. Each penny weighs 2.5 grams. So 4 pennies adds 10 grams of weight and 8 pennies adds 20 grams of weight. So this base with 8 pennies would add 28 grams of mass to a 2x2 tile. With this added weight, they'll feel like the heavy Dwarven Forge tiles.

I haven't printed this yet but it should work fine. How about try printing one to see how it lines up. Try using variable amount of pennies in the hole to have the tile your desired weight. Once I get some feedback on these, I'll work on all the other sizes, and add all of them to this Thing's files.

I did some calculations and while those magnets are awesome for things sticking together, they come to like 50 cents per 2x2 tile just for the magnets. Whereas this base solution only costs between 4 to 8 cents for all that additional and wonderful stabilizing weight.

Idea: glue thin sheet of rubber to bottom of tile (say with spray adhesive) for really nice grip. That grip combined with the force of 8 pennies bearing down on it, would create a great frictional force--they'd be almost impossible to slide around.
