Beamer Holder (upper Part) to shorten the pretty long original one. We wanted to have the projector closer to the ceiling, so i designed this mount which is also looking a little more decent, then the original holder.

its a baseplate where you connect the arm with an m8 screw. It fits the m8 screws to connect to the cross arm of a given mount. i used this one.

i printed with 80% infill, just to make sure its strong enough.
