Filament Welding tool

Save your rest of filaments! This tool need to be printed with ABS (trust me!). Print 2 times the file and you will need also a ptfe tube (4mm external diameter) and 4x M3 nut & bolt (15mm) and washer as optional. To welder both side, introduce the filament in each side, press a little bit (try to centering) and use anything to heat the ptfe (just 2 or 3 seconds could be enough to welder). I´ve been using it with success!
