So, I turned my makerbot into frankenmakerbot to make it bigger. But I have been struggling for *weeks*
to get it to extrude reliably. I want to get a triangular toothed extruder gear like this:

I know these triangular teeth work well. But, I need help finding where to buy it! Anyone know where? Thanks!
Edit: I noticed they are also called sharp spur gears.
Edit2: I finally figured out what it was!!! I had taken the heatsink off the extruder's aluminum block to try to cool the filament better. It worked great, but the filament ended up overheating within the block, getting fat and that increased the drag, sometimes completely jamming. So, I tried to increase the current to the motor, thinking that's what it needed... it ended up just stripping the filament sometimes and jamming other times. lol. A few more days of this and I probably would have taken a sledge hammer to the thing.
But I still would love to know where to get those sharp spur gears.
