Spool Adapter for Amazon Basics Filament Spools

thingiverse

Jantzenday's "Creality CR-10 Spool Adapter - Large and Small" has been working phenomenally for handling all my spool adapter needs for all my FDM printers for the past few years. I recently decided to try some Amazon Basics filaments and found that while Jantzenday's model has fit every bizarrely sized 1kg spool, it's just too short to fit the wide Amazon spools. I reduced the diameter of both the tapered end of Jantzenday's small spool adapter and nut so that it will fit the Amazon spools. My initial thoughts were that I might lengthen the threaded portion of the small spool adapter so it could be nutted on the opposite side through the wide Amazon spools, but lengthening it would require me to lengthen all the 30mm spool tubes I slide these adapters onto and that presents a problem for 2 of my 6 FDM printers, my Anet A8 and my Geeetech I3 Pro C who's spool holder designs I'm currently using, will not support the added length. Scaling down the tapered ends of Jantzenday's design allows me to use the Amazon spools on all my printers without modifying any additional infrastructure. This extra small spool adapter should fit other spools with internal diameters not less than 38mm and not greater than 54mm. If only the industry could settle on a single form factor for filament spools... The first photo shows the remixed spool adapter in orange, the small spool adapter in red, and the large spool adapter in green. This package contains only the two parts for the extra small spool adapter pictured in orange. Follow the link to Jantzenday's model to retrieve the small and large spool adapters.
