Eufy L50 (L60?) Main Brush Drive Gear

Hi Folks,

  I have an Eufy L50 Robotic vacuum cleaner. The drive gear for the main rotating brush stripped rending my robot useless. Search as I might, I was unable to locate just the drive gear. The drive component, complete with a new motor and an entirely new gear set, was all I could find. It ranged in price from 20+ on Amazon to some Chinese vendors wanting 40+ for an “original” drive set. I thought this was ridiculous for what was probably a 25-cent piece of plastic, so I designed my own. It is a direct replacement. PETG or PLA seems to work just fine. It needs to be printed at least 0.16, but I printed it at 0.12. I have had the robot running for 3 weeks now, and it's holding up well. The print profile is exactly how I printed it for strength. Aside from selling it, you are welcome to do whatever you want with it. I hope it saves you some $ as it did me.

This is a tiny gear. I would hit it with some heat afterwards to get rid of any stringing or other tiny pieces.  Also, make sure all support material is removed, or it won't fit right. 

When I was looking at the Eufy L50 parts, the vast majority seemed to work on the L60 Model as well, but since I don't have one, you'll just have to try and modify (if needed)  as you see fit. 

The pictures show what it looks like in the machine (the green gear is PLA). The original gear was white.  The blue gear is the PETG backup I printed if it failed quickly, but after several weeks, it is still going strong.  Note the dog Hair in the picture. I have two German Shepherds that shed only once a year for 365 days, so I use this device sometimes twice a day.  That is my basis for the conclusion that it works well.
