2.5mm nema 17 spacer

Bought a new ender3 pro. For the extruder stepper, this version is using a pressed gear on a round shaft instead of a D shaft and allen screw tightened gear. Bought a direct drive plate and an all metal extruder kit but the filament guide wheel and gear didn't line up. As I dont currently own a micro gear puller, I quickly sketched up a 2.5mm spacer to shift the extruder kit up enough for the guide wheel to engage fully with the filament drive gear. This shifted the motor further away from the direct drive plate so I had to replace the 25mm plate to stepper screws that came with the kit with 30mm screws. Other than that everything that came with the direct drive and metal extruder kits were all that was needed. 02/21/2022: added pics: Notice how the gear is just pressed on the shaft at the top. The spacer allows the guide wheel to line up with the gear. Remember to swap the 25mm length 3m mounting screws with 30mm length
