Improved MHP15 Pusher

thingiverse

Tired of your MHP Pusher letting you down? This revised design is here to save the day, boasting much improved reliability. The teeth on the gears now engage seamlessly, putting an end to the uncertainty of whether everything is properly aligned. And the best part? It should drop right in without requiring any changes to your shell pieces. If you're struggling with washer screws that are too small for the pusher arm, give the printable washer a try. If that doesn't do the trick, resort to using the cover piece and screw it in place. One thing to note: I haven't put the vertical orientation of the pusher arm to the strength test, so if you find it's weak, flip it 90 degrees and you should experience improved strength. The pinion gear used here is the brilliant design by Kitsune109: https://www.thingiverse.com/thing:2245550
