Self Adjusting Filament Holder

thingiverse

This filament holder is for filament that is not on a spool. It is collapsible to insert into the middle of your filament then spring loaded to expand. It is made to fit the Original Makerbot filament holder. Look at my pictures to see how I use it on my bot. Instructions Print all parts no raft or supports low qualty work good 3 Shells 10% infill Pin 1 and Pin 2 should be 100% infill high quality If you do not want to use Pin 1&2 print Center arm Bushing file and fasten with 1 inch 6/32 hardware with washers on both sides. After putting everything together use medium size rubber bands on clips on the sides of spool rings to add outward tension. I used a second mount with an empty spool to feed the filament tube. My Adjustable spool is on top of my Makerbot clipped on with the original Makerbot holder. See Pictures for Details.
