I recently purchased a left and right set of Gladiator NXT EVO space combat with the premium package, and while i love the sticks themselves and all of the features, the buttons aren't quite the right fit for me. I want to add a textured and slightly raised surface to the tops of buttons A2, B1, C1, and D1. I have access to a 3d printer and very limited knowledge on 3d modeling, so I was wondering if anyone either has a link to or file for the OEM models of the cap pieces for these buttons so I can modify them to my liking without having to make them from scratch (and not have to take apart my sticks more than necessary). Thank you in advance
