A 1/2kg filament spool I've got has a small hub diameter, so the filament supplied was wound quite tight. The back tension was enough for the extruder to pull the spool stand over!
I wanted to reuse the spool for a 50m sample of filament so I decided to make some hub packers. I'm just learning OpenSCAD so this was a useful little exercise. I printed all three segments at once with a brim joining them. I've included the photo of all three because of the optical illusion that they appear to be different.
// UPDATE APRIL 17 //
V2 of program added with code tidied and a hole for holding filament added.
STL for a segment to fit the Rigid.Ink spool also added. This STL should use just under 10m of filament to print.
I find that the last third of filament is often quite tight on the spool, so I like to manually rewind it loosely onto an empty and expanded spool.
