Paint Shaker for model paint containers

This is a device that attaches to a commercial hand held gun type massage machine from Temu. This attachment can accept 3 different paint containers which can be attached with elastic bands. I used one of the black rubber spacer grommet pieces from one of the original massage attachments that came with the gun. I have supplied a pencil drawing of the actual spigot that goes into the massage gun end from each of its attachments. If this is the same as what your massage gun takes then it will work. Also I have shown pictures of the Temu box with photos and model number so you can purchase the exact same one if necessary. I just happened to get mine from Temu. You probably get them all over. My attachment has three depressions in it to accept the different paint container types. The largest slot has another slot for the smallest container set within it. You can see this from the pictures.
I have made slots for three different paint bottles, Alclad 30ml glass paint bottle size, Testors Mod
