CKB 7E Trumpet Mouthpiece

I saw some people making mouthpieces for trumpet on here, so I decided to try it myself with a CKB 7E. It's really difficult to find one of these mouthpieces to purchase so hopefully this helps. It's one of my favorite mouthpieces as it allows me to hit higher notes while keeping tone quality, and the 3d printed version works pretty well considering it's plastic! It feels a lot better if printed on a smooth plate but it works just fine on a textured plate
