The file 'Buzz Bee Shell 3D Printer Model' is (stl) file type, size is 29.0KB.
This is my first post. It's been tested in a double shot, please print them and let me know if they work in the rapid fire. They're meant to replace BuzzBee Toys shells and are designed to mimic the dimensions of the original. They also work better (shoot harder and more accurate), accept short darts, and seem to be a solid performing shell with my experimentation. I recommend at least 20-30% infill, 4-8mm wall thickness. You CAN get away with 15 or even 10% but it becomes weak. Expect them to degrade if left outside if you print in PLA. Print with a random Z-seam to eliminate the pronounced seam bump that can affect fitment in the chamber of one of Buzz Bee's offerings.
Doesn't need supports or any adhesion support, but a brim might help. I need to sand/smooth mine of some of the print artifacts to get it to work right.
Update: Changed some dimensions to reduce/eliminate post-print processing. A more pronounced chamfer on the top of the shell and a narrower neck should eliminate the binding I used to get when loading these as-is into the chamber of one of Buzz Bee's guns.
