The remix helps with removal, usability, and ergonomics. The original model was great, printed well, but the laundry cup (while useful) was sometimes cumbersome in certain settings. It wasn't the easiest to get off and the sharper edges was not very on softer hands. 

I added some tabs to aid in the removal and smoothing used on commonly used sections (the lever handle and outer edges). I also added an additional remix, removing the laundry cup for those with limited vertical space.
