Having a 3D Printer at home and at school is great, but I've always hated turning around the 3D Printer to change the spool. In my classroom, students have almost dropped the printer off the table while turning it around. The Front Spool Holder fixes all of that! Other designs have required a trip to the hardware store, or used much more filament than I was willing to use. This design is simple and compact. The hole allows you to put in different spool pegs, just like the back of the replicator. For printing, I've had success at 10% infill, 2 shells, and no supports.For printing, I've had success at 10% infill, 2 shells, and no supports.
