this remix is built tested and works well,,the fit is tight and is very solid.. the center handle shaft is 2cm.. the ammo can be changed out very easy,, with what ever colors you choose,, i included 2 types of ammo,, the smooth original type and a more shotgun type shell.. sorry it not perfect..
i did put a metal pin for the ammo door.. i used a nail and pushed it in the ammo door is a tight fit so may need a little sanding and filing for exact fit ( everybody printing a little different)
same with connecting pins may need a little scaled based on your prints.. i had to scale mine to 98 percent :D
i printed mine in glow in the dark blue,, looks so cool in the dark :D
i have a super happy daughter :D
