Durst 609 for Slide

Hello all,

I've got a DURST 609 and I'm thinking to us it as a slide projector.
But it's quite difficult to find:

Lens tube SEITUB
Slide attachment SEIPAS

My idea is to build them by myself, so is there someone that owns those devices and he's so kind to send me details and measures of them?

Thanks
Ciao
Andrea
