The elevator arm of the Beseler 23cii series enlargers is notoriously easy to break. This simple design accomplishes the same function of the OEM part. I aim to tweak this model to be stronger and more efficient, but for now this gets my enlarger back in working order. 

Enjoy and happy printing!

For reference the part this replaces is part no. 10 according to this: https://125px.com/docs/manuals/darkroom/beseler/beseler_23ciiixl_manual.pdf
