Fix for the connecting piece of the SMAUTOP lightsabers from Amazon

I bought a cheap Amazon double lightsaber: https://www.amazon.es/dp/B0B7B5FPYN
but the connection piece has a very low quality and broke (see the pictures), so I decided to fix it. In order to get space for this fix, the speakers of the lightsabers need to be removed. I also removed the movement sensor, to keep the lights always on when moving.
I used 1/4" screws and this connection piece: https://www.amazon.es/dp/B0BDDHQPKC
It also requiered some manual adjustments and glue to make a perfect fit.
Put the cylinders up, so they do not need supports.
You may need two prints of the file "lightsabers join fix.stl" for the saber parts and the screws, and one print of the file "lightsabers join fix medium.stl" for the connection middle piece. The other files aren't necesary, buy might be used for filling the empty space in the connector.
