Reloadable spool (reel) for Inland spooless filament

thingiverse

Refillable spool (reel) with 90mm center hub and 60mm flange spacing. I wanted a reloadable filament spool design that would fit Inland spooless filament. This spool design appealed to me because it was threaded and used less filament than other reloadable spool designs I saw. When I printed it out as-is, I discovered that it had a non-standard hub diameter and non-standard width between the spool flanges. The filament spool standard that Inland uses is 90mm hub and 60mm flange spacing. I used Blender to scale up the hubs to a diameter of 90mm and changed the height of the hubs so that the 2 assembled halves would have a flange spacing of 60mm between the inner surfaces. The final assembled parts ended up being about 58mm between the inner surfaces. With the modifications, these spools (reels) have worked well for loading up Inland spooless filament.
