This mount requires only two standard screws. As pictured I used two common #4 wood screws to secure the mount to a wall. Included is an STL as well as STEP in case you need to modify this to work for your splitter. This orange splitter that I designed around is the most common form of 3 way splitter that I am aware of.
Once printed remove from the build plate and simply pry the joints into movement. With more articulation the joints will move more smoothly.
I printed this on an Ender 3 S1.
