I tried Glennbeekhof's spool holder, but it did not fit on my Fabrikator, so I redesigned it.

• bigger slot to fit on the machine without force
• connection bar in the middle of the slot
• the rod is now a little deeper (3 mm) in relation to the connection part
• the rod is shorter (65 mm, better center of gravity)
• visually appealing, smaller cover plate

It fits perfect for my Das Filament 800 g spools (outer diameter 200 mm, inner diameter 52 mm, spool width 55 mm).
