Replacement "Bullets" for Crosman SR357 BB Gun

I designed these for my mom after she lost one of her original ones. I used a ballistic chronograph to compare to the originals and was unable to see any difference in performance.

Printing notes:

• The casing is printed in PETG, and the tip in TPU-95A
• 0.2mm layer height
• Perimeters used to achieve 100% infill
• Used supports for the tip
