Printed it and added a custom bed.
What's this blue material ? Is for ABS to avoid wrap ?
On the bed? Cause if that's what you mean it's blue painters tape to promote adhesion, I have since switched from this setup though.
What are you using to improve adhesion with ABS filament ?
You need a heated bed, no way around it. I was going to sell a PrintrBot Simple extended heated bed kit but never got around to it.
