How can we better address the similar problems that we all are all coming across during the our sixth week of class?

I have noticed that there are some issues that all of us are starting to face in the finishing portions of our tinkerCAD work. Things like clips, hinges, and male/female plugs are without a doubt the hardest part about creating with the three-D printer. I am still having troubles with the hinges for my glasses frames, and other students around me seem to be having similar problems to solve. Grant is making maraca shakers and would like to have the bottom clip into the top so he can add beads, but needs it to hold steady when someone is using it. All these little complex problems can become huge problems when three-D printing. Working together in specified groups or more peer-assisted lab work could help keep our projects successful and our troubleshooting to a minimum.
