Toy Project

I know there are a million... maybe a billion similar products... but to print a toy —a building one— at home with all its components... screws, nuts, arms, brackets... etc., seems like a successful .... Toy project. This project will be open to everyone to add to and modify... so everyone is welcome to look at it and contribute. I apologize if someone else thought of it and designed it before me; the truth is, I didn't search... I went straight to the design... so the idea was originally a gift for my grandchildren. Note 1: If you feel this design is affecting you in any way, please let me know and I will delete it all. Note 2: The list of parts is too long, and the names may be meaningless... Look at the layout... before printing... It's best to choose a group and then print it. Note 3: There are definitely no supports... and nothing to buy... just your filament and printer. Note 4: More parts will be added later... I'm still editing... deleting... and correcting... please bear with me. Thank you Update 1: I forgot to add the screwdriver... and these are its files.
