Extended pusher with longer rod, better spring holder, and a top to help prevent misfeeds. This is my latest iteration, last one did not print well and was super tight in my stryfe, so I shaved it down a little bit. Definitely use supports and do a pretty high support density. Let me know if you have any questions or if you have a good print!
Use lower support spacing (.3mm or lower) to ensure all parts get printed nicely. Will probably require sanding.
