Glueing will not work. The first screw that enters, will break it again. Reproducing these: Login to view image   Or at the PSU side: Login to view image  

The 3D printed part is a great solution! If you still want to try repairing the old part, a stronger glue, added reinforcements, or a combination of both might work. Below are a couple (of many ways) to do this. Login to view image In the first picture. The outside of the post is roughed up so a mechanical bond with the glue can be made. My favorite glue for this type of repair is original JB Weld. In this repair the epoxy itself provides all of the strength. In the second picture, metal pins are heated and pushed into the plastic. The melted plastic holds the pins in place and the metal provides the strength.  Another option could be to glue a thin walled metal tube over the post. For any repair, be sure that you clean out any material that may have gotten into the screw hole. Lubricating the screw can also reduce the stress on the repaired part. None of these options will look as good as the 3D printed part, but once the speaker is reassembled nobody but you will know. Glitch

My experience with glueing the parts together with supports around etc is, that the plastic is so brittle and it easily breaks again at another place along the pillar. To prevent breaking I always start to search for the thread and use some grease or just wetting the screw to carefully turn the screw with the minimal amount of force back in its place.

Thanks BeoBuddy ! I agree on the 'brittleness'. The material all over is quite vulnerable after all these years. After it happened with one screw, I put just a bit of WD40 in the other screw holes. Keeping the screw vertical and screwing slowly works quite well. Anyhow, if one screws slowly without too much of resistance, it works well. For all other cases, it is indeed better to create new brackets/stands. I think I might also do this on my 3D printer. === By the way, did you see my PM to you?  

Hi Beobuddy, Are these models available somewhere? Would be of great help to me, thanks!

Jaspers1996, You can buy them for your Beolab 8000 at www.dksoundparts.com ( circa € 20,- a piece)

Thanks @Jaspers1996 I have a 3D printer, so having a 3D model would be my preference.  

Yes, agree. A STL would be great.

For most people who overhaul their own Beolab 8000 once it seems to me more convenient and much cheaper to just buy a new holder, versus the cost of purchasing a 3D printer or commissioning someone who has one and who first has to create an STL file
