Thanks for the ideas for the printer guys. The "packing tool" and the other tools were modeled based on reference images I gave Filipe; we were planning on going back and updating the models later on. The idea was to replace the roll of tape with a roll of decals instead, although I'll work on finalizing the design for it soon.
Btw, I might be able to post a new update soon, and show off some cool stuffs. It's taking a while because I'm completely rewriting the brick system and rethinking how they're made, so that brick creation will be as easy as possible for add-on developers.
