- First I put some Sugru between all parts of the handle and put them together (cf. red arrows on pic 1).
- After that, I put some Sugru on the bottom of the handle and pressed it several times against it to get a good connection. Then I formed the Sugru to fit through the hole in the glass and pressed it flat (the round hill in the middle of the pic 2).
- With the remaining Sugru I formed 4 arms to stabilize it even more.
After hardening the Sugru is well connected to the plastic and the glass. Not even hot steam can soften it or enable any movement, I use it for a month now.
All in all I don't even needed 1 pack of Sugru (5g).
