After playing in the server alot, I thought about something small and interesting you could make. A little brick pack with 2 or 3 bricks. One that refills your ammo and one that heals you, or gives you medical supplies when you activate it. I was thinking the medical supply brick would look kinda like this

The brick itself would appear to be floating, to make it look like it is hanging on the wall when placed against it. Might be cool to have. If anyone else made it, it might now work with your ammo system.
I know someone will mention the ammo and healing bricks from the zombie mod. But those are for the zombie mod, and they use a different ammo system.
