Height Adjustable Pebble Wiper V2.1 for Tool Changing 3D Printers

I recommend this version as it can adjust to different hotend lengths and allows you to use a more reliable, however complex, wiping routing.

You can either use a stepper motor with an integrated leadscrew or use a standard stepper motor with a coupler to attach the lead screw.

I have included SLDPRT, STEP, and STL files for regular E3D Tool Changers using both fancy and cheap servos.

BOM for Pebble Wiper V2:
Printed Parts (I recommend printing in Polycarbonate, but other materials may work just as well, depending on your use case)
Servo (I recommend the KST DS215MG, a servo lead extension may be required)
Nema 17 Stepper Motor with 130mm Integrated Lead Screw and Trapezoidal Nut (I used the Z stepper and nut from a Prusa i3)
100mm LML12B Linear Rail + Carriage
Silicone Brush
Adhesive Backed Metallic Strip
*Optional: Metal Servo Arm

For the metallic strip any adhesive-backed metallic foil should work, such as HVAC foil tape.
