3d fillement brake system

This brake system wil work with every printer but watch out with the fillement  i use leapfrog  it commes on black spools that fit exactly onto the holder you can use it without the adapter and brakering in the future i will come out with differet adapters and rings for different rolls ( or just ask )  you need to tap a m6 hole into the complete holder and a bolt with a rivet holds it in place ( tighten the bolt for more braking)i print with this system for 1 year now without any error  ( about 80 rolls so far)   use 50 % infill or higher for good strong results good luck printing without any fillement errors  chef
