I hobbed the original drive wheel with a 3mm tap. It may work without hobbing, but I haven't tested it. I tried modifying the drive wheel first, and after that did not help I created this.
Yes, it is based on Bart's and few other designs floating around here on Thingiverse. I used it for about 4-5 hours of printing so far and it works great.
After using this mod for a couple weeks, this mod works great!
