Ender 3 V2/V2 Neo Filament Guide and Z Stiffener

This is a simple model to help stiffen the Z axis and guide filament cleanly on an Ender 3 V2 printer. It may work on a regular Ender 3, but I am not sure as I do not own one.

Assembly

1. Lightly tap the bearing into the larger hole of the model until it's completely level.
2. Remove your Z axis leadscrew from your printer by loosening the stepper shaft coupler at the bottom and pulling it upwards. Turning the leadscrew while doing this may help.
3. Remove the end cap from the top of your Z axis aluminium extrusion on your printer. 
4. Insert the top of the leadscrew into the bearing in the filament guide.
5. Slide the T slot shape of the filament guide into the aluminium extrusion, making sure to keep the bottom of the Z axis aligned.
6. Put the leadscrew back into the Z axis nut and turn until it goes fully back into the stepper shaft coupler.
7. Tighten the coupler back to how it was before

If you don't want to bother with Z axis stiffening, you can leave out adding the bearing. Otherwise, you will need a single 608 bearing (22x7 outer dimensions).

Printing

• 3 Walls
• 10-20% Infill
• Supports needed if using the no included support model

The model provided (marked “WITH SUPPORT”) has a few small sacrificial support pieces at the bottom of the T slot. These are meant to be broken off after printing. They reduce material usage and make it easier to remove supports after printing. If you want to add your own supports, I have provided a seperate model without them.
