Upside Down Filler double Slot Adapter for Original Creality Ender 3 (& other) Spool Holder

Adds a second spool on the Ender spool holder using Filler. Additionally helps to balance the weight on the Z axis. I rotated the connection part by 180° to be able to use it upside down. Counterpart: https://www.printables.com/model/1172536-filler-filament-holder-upside-down-fillerbracecrea
