Dumb Question

I am patiently and excitedly waiting for my first 3d printer kit to come in the mail (Acrylic Prusa i3) and I have been doing a bit of research on 3d printing so that I’ll hopefully know what I’m doing by the time I get it all up and running.My question is in regards to bed adhesion with PLA filament; I’ve read that hairspray, and “blue painter’s tape” are the most common solutions for ensuring good adhesion for PLA plastics.Does the painter’s tape literally have to be blue? I’ve got a whole bunch of the green painter’s tape sitting in my garage, and normally I wouldn’t ask such a dumb sounding question but it always specifies the blue kind. If so, what’s the difference? http://ift.tt/1XwX90L

WTF? Any idea why my print would look like this? Should be a regular print. She’ll thickness of 1. Forgot to save the setting but I’ve never seen a print come out like this.

What uses does flexible filament have?

I’m curious about what kind of interesting uses flexible filament has and if anyone has made anything really cool with it. I’m thinking about getting some to print some rc tyres but I’m wondering if I could use what’s left over to make something cool :p let me know if you’ve worked with it! http://ift.tt/23i2FEK
