I wanted wider contact points to feel more like my DJI controller. I also added texture to the tips to make it feel more like my DJI controller. The initial design height felt too tall for my hands so I made them in three different heights. All have been print tested and work. I ended up liking the short version the best. 

Printing and mounting is pretty straight forward. I print in PETG for sturdiness. I originally tried a Silk PLA but the break on the print bed. They snap on the controller just as smooth and easy as the original design.
