My original BB speed loader (or fast loader) rod / trumb armature broke, so I designed a new one to be slightly stronger.
Print the "split" version it in ABS or PET-G, glue the two sides together with super glue, finish it with a file or sanding paper and off you go!
TIP: If the BBs don't enter the exit chamber smoothly after releasing the rod (i.e. you have to shake or wiggle it to enter), then slightly adjust the upper angle of the tip with a file, so it would not be on the way.
