modular brick mould

inspired by https://www.youtube.com/watch?v=r39dvtQBs44 these guys and their video's
modular brick making mould to cast bricks. might make a version that can be paired up to make several bricks at once.

https://www.archtoolbox.com/materials-systems/masonry/bricksizes.html chose modular brick size from here, not sure what nominal size is but i chose the specified size.

might need to be scaled down a hair to fit on the bed better. would probably suggest making this from 2x4's but its a good place for information
