PLEASE RESPECT THE LICENSE AND GIVE CREDIT TO THE DESIGNER
A fixed Drive block only for flexible filament, made for Makerbot The Replicator. It makes sure the filament is tightly supported below the feed mechanism together with a modified M6 tube (PTFE tube inside). Ball bearing 11x5x5.
I developed this filament feeder to be used with my own TPU filament, letting the filament do it´s own pressure against the drive-wheel.
Please also check out my unuiqe UV-stable, flexible and conductive filament called ETPU 95-250 Carbon Black filament.
Don´t need the conductivity? Well the conductivity is great for some things but perhaps not your first choice? Then consider this:
This filament will give you some really nice benefits if the conductivity is not an disadvantage for your 3D printed design:
•The material composition eliminates “stringing / webbing” issues.
•The hardness of 95 shore A and the carbon black filler makes for great print abilities.
•The carbon black filler is an excellent UV stabilizer thus the prints are built to last in very harsh environments.
•The matte black surface finish has a very exclusive look.
•The material feels very nice and dry to touch.
•It´s not too stretchy and will do great for timing belts etc.
