3D-printable split filament spool with threaded joint (135 mm)
This 3D-printable filament spool measures 135 mm i diameter (5 inches). Fully winded it contains approximately 350 grams of filament (12 ounces). It fits shafts with a diameter of 16 mm or smaller.
The spool is made of two separate parts with a female and male threaded connection. The design can therefore be 3D-printed without the need of support material.
As an accessory we also supply an axel which can be used with a power-drill to facilitate winding of new filament onto the spool.
The video above shows how to assemble the 3D-printed spool and use a power-drill to fill it with TPU flexible rubber-like filament.
