Mounts to most 2020 Aluminum extrusions. Can be used on Folgertech 2020, Tevo Tarantula, most deltas, Etc.
Main holder rides on two internal bearings for a nice smooth roll. Can accommodate several spool sizes.
If your slicer has a "Supports from build plate only" option, turn that on.
User higher infill for strength. I recommend using ABS or something stronger.
Additional Materials Needed
Attach the threaded rod to the main arm assembly, with a nut in back and a nut in front, securing the rod to the arm.
Push a 608 bearing into each side of the inner spool threaded assembly. Slide assembly onto threaded rod and secure loosely into place with another nut.
Assembly of a similar holder
Optional Post Processing
I like to sand down the grips on the spool holder as they can be semi sharp off the bed. 600-800 grit sandpaper around the edge of the grips helps.
I also go around the threading with a sharp tool (razor, knife, etc) to remove blobs. Screw and unscrew the two spool holder pieces together several times before mounting. This will aid in smoother threading.
