Anyhow, you make 2.85mm filament and not 3.00mm although you mention 3.00mm on your site. What's up with that?
3D printers with a Bowden tube set-up, like the Ultimaker, work better with 2.85mm filament. We produce 2.85mm filament as 3.00mm to keep things simple. Our 2.85mm filament have a tolerance of 0.05mm and work on all 3D printers for 3.00mm.
