Filastruder is a filament extruder designed by a UF engnering student and I'm wondering what you guys thought of the product? http://www.kickstarter.com/projects/833191773/filastruder-a-robust-inexpensive-filament-extruder I have heard there are issues with these machines (in the past) creating consistent diameter and having air bubbles in the filament. I also am wondering if you calculate the electricity used and the time and labor is it worth the investment? The main appeal to me is to save money on filament and to be able to reuse wasted filament from bad prints. What do you guys think?
