I have to say, I had just about given up on my TOM. all I was ever printing were things to test if the machine was still working, and those things took forever, and printed so inconsistently that it just wasn't worth my time, and totally uninteresting to my kids. I spent hours and hours adding a second print head for dualstrusion using dissolvable filament so I could print some 'moving parts', hoping that would make 3d printing magical, but it was just another exercise in patience with a payoff that fell short. Sailfish has brought our TOM to life! it's now running every chance it gets (thank god because my collection of filament would have been wasted), already made field trips to classrooms at school, and we're working with teachers and friends to finally have this be a walk up device for imaginative kids. THANK YOU!
