A quick fix for when the light 1kg spool start to be pulled by the extruder instead of unrolling from the spool rollers (thing:33573).

(That's why I prefer to use 2.3kg spool otherwise)

The 50x50mm plate is to be used with a 200mm extrusion profile (and two 20x20 test part as a way to keep the spool on it)

The other part is for 8mm threaded rod, should work but haven't been tested.
