Boom Toob Shells

prusaprinters

Update: Added a new shell type, called the 4-Boom. I found that a small sized shell could be made to accept a MXL dart. This shell type is almost exactly the size and proportions of the real-steel 4-Bore cartridge. These are a collection of shells I designed for my Boom Toob blaster. There are currently two shell sizes, for which I included an adapter. Currently, there are 3 shell types: sextuple short dart, triple Mega, and single Mega XL.If some darts not firing from your shell, it likely indicates that either your printer or dart selection is inconsistent (it doesn't matter whether the darts are new or old, as long as they are all the same).This can be fixed by either changing your dart selection, tuning the printer, using a drill bit the same diameter as the dart to bore out the chamber, or using sandpaper glued to a dowel to clean it out.If your printer struggles with tolerances, you may need to sand the shell adapter to make it fit properly.None of these shells require supports or post-processing (unless there are issues)I have also included a (pretty awful, but functional) shell carrier compatible with tactical webbing. It is currently only compatible with the smaller shells. This requires some support Note: with the Mega XL shell, you can leave it in the blaster, and muzzle load with bare darts and prime underhand to prevent the breech from opening. Note: The shell adapter can be twisted counterclockwise once inserted into the barrel to fully seat it in place. If it does not fit or cannot be turned, try removing it, rotating it, and inserting it the other way, to see if it will work that way before sanding/modifying. These shells do not accommodate every ammo type available, only the ones I frequently use. Feel free to make other shells for different ammo types. If you upload them, post links in the comments so others can find them.
