Fit Testing Block

How much space do you need to leave between parts in your design for them to fit together? Print this set of **blocks** and **pegs** to help get an answer.

Start with the `Block_x_2.stl` unless your process is super-accurate. Then print the pegs. By testing the which hole the peg fits in, you'll get a sense of how much space you need to leave in your design for parts to fit together.

The `BlockPlus.stl` is useful for more accurate printing processes, like SLA or SLS. Only rarely have I needed the negative sized holes in `Block.stl`
