The file 'Spoolholder 608 Blocker 3D Printer Model' is (stl,obj) file type, size is 57.8KB.
The blocker is intended to prevent the part holders from leaving the base and to stop everything from moving towards an enclosure. This could happen when the extruder has to pull too hard.
It will (optically) fit best if you don't use rubber feets.
