NOTES:
We are planning to get many of these parts molded so "makers" can buy em cheap and use for their projects. We need your feedback --
What other parts would you like added to the library?
What colors should different parts be molded in?
What would you build with it?
Would you like any parts modified?
We welcome other comments and suggestions
