Vertex K8800 diagonal rods

Hi Community. I found a Vertex K8800 with some missing parts on the street. I found some information for the missing parts and replicate those. Except the diagonal rods. So i went to some 3d printer stores in my area and they all told me, i should bring the Vertex back and buy a 3d printer. Velleman printers are garbage.
So i won’t believe that until I tested any printer.
But my big problem is, this printer is out of life? Is that true, Velleman doesn’t produce any more spare parts for this printer?
If so, i have to make it by myself. Could anyone tell me the length and the diameter of these diagonal rods (with the magnetic balls)?
Greetings from Switzerland

Dear @Leckerbierchen

Indeed, the printer has been out of production and removed from our assortment for some time due to market competition and pricing, not because of quality issues.

We can still provide you with additional diagonal rods if you need them. How many do you require? Please create a ticket on Customer Care – Velleman – Wholesaler and developer of electronics
or click on the green customer care button on our website: https://www.velleman.eu/ for this request.

Thank you very much. Sadly to read. I like the design. I hope I can make it to work. I want to prove to the last dealer that the printer isn’t that bad after all. The printer seems to be have a big fan base. I found a conversion to uniball rods and other hotends. But I want to test the printer originally.
Thank you for your help and have a good day.
