I am seeking the advice of some of you masters. I am working on a MOC and I need to connect a slope to an axle and have it go through a beam and be adjustable in and out. I also need the slope to be secured well to the axle. It seems that some new parts are out this year that would help, but I don't expect them to be available for quite some time. The beams must face holes up but a 90 degree twisted connection would work between t beams that are holes up.
Here is a link to one of the new beams 6321716 that would make life easier:
Here is my initial concept, however the slope is not secure in place and could easily be knocked off and the assembly is quite clunky. The only requirements are that the beams remain rigid and the slope is adjustable

Open to any ideas that may use some parts I don't have yet.
Thank You
