Compact Bearing and Filament Guide for Ender 3 v2

**Note**

This thing is designed to line up with the red aluminum dual gear extruders found on Amazon. The filament hole is about 10mm higher than the stock one.

Compact bearing guide and runout sensor made to fit within Creality Support Rods, uses:

1- KW12-3 Roller Lever Arm Micro Limit Switch

1- 608 Bearing

2- bearing spacers from this thing: https://www.thingiverse.com/thing:3052488

2- m2.5x20 screws with washers and nuts for limit switch

2- m3 screws for attaching to lead screw plate (might be able to reuse old ones)

V2 adds gussets in front of the runout sensor to reduce bending at the screw holes connecting it to the lead screw plate (this thing was printed in PLA, and bearing guide bent upwards slightly over the course of a few hours of printing, PETG should hold up better)
