Nerf Cycloneshock cylinder mod, 3 regular + 3 mega darts

A cylinder for shooting both mega darts (3) and regular darts (3) with the Nerf Cycloneshock. Regular ones have a lot more power behind it with this mod. The only other alteration is the removal of the air restrictor.
It is a remix of Horsengineer's cylinder, with his the barrels were too short (less accuracy) and too narrow (could be my printer). I always take 5mm margin, his model had about .15mm margin. I also added some fillets. Printed at 0.1mm thickness, 10% infill, 48mm/s 11hours, PETG.
