I'm making these up for my Intro to Engineering Middle School class, and they are wonderful except for one problem I'm having. The gear base pegs keep breaking on me at the slightest touch! I've even tried them at 100% infill with no luck. I'm running a Wanhao Duplicator clone, PLA at various temps up to 215. Any suggestions? I'm brand new to 3-D printing unfortunately, only had the machine for 2 weeks now.
