Adjustable Filament Spool Spindle for 3D Printers

thingiverse

This was designed to replace the stock, small-diameter spindles on the Lotmaxx Shark SC10 v2 Printer, but I suspect it may be compatible with or adaptable for other printers, too. The cones allow it to adjust to the inner diameter of many different filament spool sizes. It may not be necessary, but I did not like the way the spools would swing during printing because of the way they hang on the stock spindles. With this spindle, the spool is held steady and filament rolls off smoothly, avoiding any extra forces pulling on the filament. It may also decrease the likelihood of tangles.
