Short edges

It's something to check in the code - I don't know about it.
Use such small size is not good too in case you would like at some point call [Body]Cleanup command.

Wouldn't you work with a different scale - lets say 10 units=1m and then at the end you just create Bound Box which the "L" length is the grater dimension of you want for your project. Then select all and use Scale to Bound Box->All. It's more complicate to me explain than your run the action.

Just an Idea that I already used.
