Cute Tiger 98K Shell Bridge

Water gel pellet firing version, low cost to print yourself. Compared to purchased ones, the airtightness might be slightly worse. Original shells score around 60, while the printed ones average around 58 after many trials, a drop of about 2 points. The model contains a total of four shells, made in 7mm and 6mm calibers. Both calibers have two types of bottoms (chamfered and non-chamfered). In practice, they are quite similar. For the 6mm caliber, be careful; since the pellets are hard, it's best to polish them more smoothly, otherwise, misfeeds will be significant. If you mind, just delete it during printing. Finally! Space is reserved at the bottom of the shell, requiring a silicone tube to be placed to ensure airtightness. Purchase a silicone tube with 4mm inner diameter and 7mm outer diameter yourself. Cut it to 5mm length and insert. The reserved length is slightly more than 5mm; if the bottom silicone is flush with the bottom, it will cause problems, preventing the shell from being ejected.
