SledgeFire Shells (that work with STOCK BLASTER)

I have three SledgeFires. The first two I cut up and modded, and the third i found in the thrift store with TWO ORIGINAL SHELLS. I want to keep this one stock… But that empty slot in the stock shell storage made me anxious. I tried the printed 3D shells, but the ones I had only worked with a totally flat breech, not the weird little raised lip that pressed into the original rubber seal. So I decided to make my own. It comes in two parts. the first part that holds the darts. It even allows the little things that check to make sure a barrel has a dart in it to function. The second part is the thin seal. It glues to the bottom and works rather well. My MAIN goal was to make the shell as much like the original shells. SO, I made the barrel rather big (13.6mm) and made a 12.7 mm “collar” at the bottom of the shell barrel to capture the dart. I did this to not only make the shell fire any diameter dart (whether brand new and firm or old ad squishy), but to allow the smart AR to work. PRINT S
