Now may be a good time to upgrade to a metal lever.

Here's an aluminum version of the part that will work I took this info from the Wiki. You'll need to either take the bearing from your old extruder, or buy a 4x10x4mm bearing to use the original gear and not have to re-calibrate your extruder settings.

I have several upgrades in the queue for this weekend once my M3 hardware kit comes in:

• The 40mm fan for the controller board: https://www.thingiverse.com/thing:1867169
  
• The Z-Axis rod stabilizers: https://www.thingiverse.com/thing:1775502
  
• The zero-offset mount: https://www.thingiverse.com/thing:1848402
  
  (Note the above designs are all three by USWaterRockets, who seems to have exceptional engineering skills, but I haven't installed them yet. Hopefully, this weekend and I'll post results)
  
  Another one I'm considering next:
  
  
• Belt tensioners: https://www.thingiverse.com/thing:1697171
  
  Here is the E3D-v6 adapter I currently have on the printer:

  Note the above design is just a quick-and-dirty solution; the author even states this. It works and will get you what you need to get things going with the new head.
  
  Other upgrades I've done:
  
  
• Upgrade the firmware and set the PID values correctly to control temperature better: https://hackaday.io/project/12696/instructions
  
• Replacement filament feeder: https://www.amazon.com/gp/product/B0196B285I/ref=oh_aui_detailpage_o05_s01?ie=UTF8&psc=1
  
• PEI print surface (two parts):

• Cork insulation under print bed (I attached it using the adhesive from the above order): http://www.michaels.com/artminds-cork-roll/M10171279.html?dwvar_M10171279_color=Natural#q=cork&start=6
  
  Here's the E3D-v6 printhead I bought and it's worked well: https://www.amazon.com/gp/product/B01H4V2QEK/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1
  
  Disclaimer: I'm new to 3D printing. This is my first printer and the learning curve is steep. I may look back on this posting in a year and think "what an idiot I was doing <this>". Take my advice with a grain of salt, as I'm muddling through this whole thing. YMMV

You should also get these: uxcell® 5 Pcs Silver Tone 10mm x 4mm x 4mm Sealed Premium Flanged Ball Bearing https://www.amazon.com/dp/B00G9W20VU/ref=cm_sw_r_cp_api_lJ-vybPV8A1NM

You need the bearings instead of the one in the above kit if you keep the original drive gear on the machine. The new kit has a new feed gear, but it will change how much is fed, requiring you to recalibrate your printer.

The anycubic one looks like the way to go since this is only temporary. The pressure is still on the plastic so it'll eventually break. Can you point me to the instructions you used to replace it? Thanks

Be careful doing this.

I think i ruined my feeder bearing doing this and had to replace it with this

Was not a simple procedure... but worth it in the end

I know that I had the arm on my extruder crack. I replaced it with this one and it's worked great ever since.

As an examples: https://www.amazon.com/Anycubic-Extruder-Aluminum-Reprap-Printer/dp/B0196B285I/ref=sr_1_5?ie=UTF8&qid=1472749839&sr=8-5&keywords=mk8+extruder

There are plenty of printable designs out there too, but the metal ones are so cheap I don't see much of a reason to go with a printed one unless you want to modify the design.

You want this. https://www.amazon.com/dp/B0196B285I NOTE: Requires two M3x20mm screws or two M3x25mm screws and maybe a couple of M3 washers that are not included.
