Ender 3/Pro Side Spool Mount - No extra hardware required. Simply drop the T-nuts into the slots (I suggest putting them in the wrong way round to spread the compressive load over a slightly larger area), then tighten the screws lightly. This design should mean the spool is held far enough away from the printer such that the spool can be placed centrally next to the extruder (rather than offset whcih leads to the fillamet entering the extruder at an angle). This may also work on other Creality printers with the same structural extrusions.
