Simple spool holder

Update.
I designed this for my custom built printer which is heavily based on the X3. However, when I printed one of these spool holders for my genuine X3 it seems the spool maybe too close to the extruder to work properly. I have added a design that offsets the bracket to allow more room. The "simple spooler" is the original design and the "X3 spooler" is the offset version.

A simple but versatile spool holder, fits to extrusion, just insert the arm into the bracket depending on the mounting orientation. It should be a nice tight (hammer) fit, if not then a drop of glue will hold it. Fit to a scrap of wood for a free standing holder, screw it to a near by wall to save desk space, under a shelf etc etc.
