Multi-Point Control Fork CL-6134. Mine broke so I modelled it and re-created it using TinkerCAD.

Available for purchase from OGS Canada. I believe OEM uses HDPE? https://www.ogscanada.ca/multi-point-control-fork-plastic-insert-only/?searchid=0&search_query=window+lock+guide

Print using PETG 100% infill. Will not work with PLA or ABS! Significant flexibility is required from the plastic to be used.
