Ender 3 V3 Top Spool Mount with Runout Sensor

The block was made by Scratch3DPrinting. Find it on MW! I remixed it to have a hole to mount the runout sensor.

• You will need a longer filament runout sensor cable.
• 2 M4x10 screws to mount the bottom side plate for cable management. 
• 1 M3 Threaded insert to mount the runout sensor.
• 3 M3x25 or M3X30 screw for filament sensor and the Spool mount block.
• superglue

Remove the filament spool from the side and remove the 2 locking screws for the arm as you will need them later.

Put the printer on its side remove the back cover. Remove the old filament runout cable. And install you longer one. Put bottom cover back on. 

On the spool mounting black there is a hole on the from by where it says ender. this is where the thread insert goes.

 Install the spool mount block. 

Use the 2 M4X10 and screw down the plate that is Side Bottom.

Super glue the connection point for the next piece that has the curve in it.

Next super glue the top piece.

Now use the arm locking screws that came with the printer that you removed off the side and line up the holes from the top cable management piece. install you arm and spool holder.

if the arm can come off very easy. tighten the bolts down a bit more.

Use the spacer for the filament sensor. Don't over tighten this screw because you want the runout sensor to move as the print head is moving. 

Now run your new extra long cable up the side and locking it into the locks on the cable management clips.
